Slow Vlan-Vlan Performance on c2758 (Supermicro 5018A-FTN4)
-
Thanks for the reply. Yes - powerD is enabled and also MBUF has been raised to 1,000,000.
-
couple of things I see which could be your problem (Or be no problem)
1. How fast hard the hard drives in the machines that you are testing? ~60 MB/s seems right.
2. The VLAN tags on your packet will take away from the payload which will lower your speeds
3. Try using SMBv3, there is a dramatic speed performance boost (Windows 8 + to Windows 8+ Server 2012R2 supports SMBv3 -
Thanks for the thoughts:
1. HDD speed is not the limiter. Copying to and from NVME SSD @ 2050MB/s on computer #1 and 4x RAID10 sata SSDs that reads at 1000 MB/s. I've tested it on a separate 10G line and I get about 700 megabytes per second (not megabits).
2. How much does VLAN tagging affect speed? Understood that a portion of the packet is occupied by the tag.
3. Good point re: sabma. That's why I wanted to test with iperf.
-
Quick update on the matter.
I ran a separate iperf test on the interface reserved for management. This interface is unique because (1) it is not switched through the Juniper ex2200 and (2) it is on the Intel PRO/1000 PT card, not the onboard NICs.Speeds were roughly the same at 570 mbits/s. Although this does not solve any problem, it eliminates a few variables, which is useful.
Your advice is appreciated.

What kind of hardware are you running. It's interesting that when you ran the test from a port with no VLAN tagging you are seeing a 100 Mbps increase in performance. How ever I would believe that you would want to see something closer to wire speed. I will run the test on my hardware to see what I get. I am running a Core i5 with 4 GB of RAM. Also My LAN is built in and I'm using VLANs as well. I also have a intel dual port Gigabit PCI-e NIC.
I also have a Cisco Router 2821 with two Gigabit ports I will set up sub-interfaces on that router and then connect that to a gigabit switch and see what kind of speeds I get with that. I will run the iPerf test from Windows Server 2012 R2 and a Windows 10 machine with a core i5 processor as well. I should have the results in a day.
It will be interesting to see if I can get routing at wire speed?
-
A cisco 2821 will not do line rate with routing.
This is simply seen a cpu with linux and some asics added for certain functions.
And the cpu is a 64 bit risc processor at 466 Mhz (http://pmcs.com/cgi-bin/download_p.pl?res_id=4607&filename=2020578_004405.pdf)For my work i have few hundred in the field, and there we use them up to 80 mbit/sec.
But we use QoS, some ACL's, BGP, ip sla and shaping.To add something usefull. I have tested with my supermicro a1sri-2758f pfsense from lan to wan with no packages and saw about line speed. (With version 2.2.4) that was with 2 of the onboard nics. Simply inserted the pfsense before my download pc to test all the pc applications.
Copy was from PC to NAS.A Lagg port will not load balance a single session per default. It will be one link only, unless you run a round robin algoritm. So test from station to station will per default use 1 link out of you group from 4.
A lagg would be usefull only with multiple stations going over it. Or windows with smb 3.. -
I also have a Cisco Router 2821 with two Gigabit ports
This is doing the real work in silicon, Cisco and other big vendors are often using ASICs or FPGAs
to do that job very fast and offloading many tasks from that CPU inside! That is not a real comparing
because pfSense is a pure software firewall. If you want to compare something likes this against a
pfSense machine go and buy a Chelsio adapter that is also owning a ASIC/FPGA on it.There are two different versions of the LAGs. One is using the LACP this is the dynamic one and the
other will be set up manual by hand and is the static one.But then you will be also able to set them up as active actice and active / passive and this might be
more important as you might be thinking about. If you are using active / passive it will be working
likes the following. If the first from 2 till 8 wires are broken or not working, the next one will be in
usage and so on. But if you now using the active / active method it is pending on the algorithm how
it works, because in normal the first of 2 till 8 wires or that line must be fully rendered or saturated
before the next one will be in usage!!!!!!!!!!!! So you have now 4 wire in usage and set them up as
2 sending and 2 receiving together with the round robin algorithm that is spreading all packets
consistently over all wires or lines in the LAG you will be seeing other numbers and reactions. -
Pfsense is set to lagg protocol "LACP"
And Juniper ex-2200 is set to "LACP active"
From what I can gather from the packet stats on Juniper, packets seems to flow somewhat evenly across all four lines. Yes, I am aware that 4x In LACP means up to four separate one gigabit connections, not one four-gigabit connection.
If anyone wants a few Juniper printouts / data/ commands, I can provide. I think the issue is my pfsense configuration, however.
I've run iperf with 4-5 different hosts now. All yield about the same result.
I was able to get a 100MB/s transfer over samba yesterday, but iperf is still showing 500mbit/s.
Any suggestions for what's going on?

You test perhaps single session with iperf.

I set the "-P 0" flag on the server and the "-P 4" flag on the client. Is that right?
With pfsense as server, I get 112 MBytes/s and with pfsense as client, I get 219 MBytes/s. That's strange…... I'm not sure how I even reached 219. To be honest, I'm not sure how to interpret these results.

Well try 8 streams than.
It could be that the packet flow is not optimized to come from the firewall itself, but more to push data through from lan to wan.
I assume if pfsense is the server and you send data to it, all rules will have to be inpected, and you hit on the last one (logically)
Perhaps move it to top for test and see if it improves, than you know if going through the rules has such a impact.With pfsense as client it is pushing data out so no filters at all i assume.
And that 219 is the total of the 4 sessions that run in parrallel.
If i think about it, pfsense its lagg seems to work if the total is above 125 MB/sec it must go over more than one link.
If that does not work for a pc connected to your switch, the switch does not distribute the session over multiple links. That is default for 1 connected pc.
You could test in parrallel with 2 clients against the pfsense server.
If the total of the 2 clients goes above 125 Mb/sec the traffic goes over more than 1 link.(You will never see 125 MB/sec in real world over 1GE links)

When I test pfsense acting as server, and two clients sending data at the same time using this:
iperf -c 192.168.10.1 -P 64 -i 1 -p 5001 -f M -t 10Then the result is that both clients each have the following result:

[SUM] 0.0-10.3 sec 1162 MBytes 113 MBytes/secWhen I run the following, they each only get 56.9 MB/s
iperf -c 192.168.10.1 -P 1 -i 1 -p 5001 -f M -t 10That tells me that LACP is working because I could saturate the line with -P 64
Why does a single -P stream not saturate the line?
-
It seems to me the lacp is working on the pfsense side.
I do not know juniper, but with a ciso you can only do lacp if the physical interface members have the same configuration. So port speed, duplex, mdix etc.
Perhaps you can check that ?Read this one: http://www.juniper.net/techpubs/en_US/junos15.1/topics/concept/interfaces-hashing-lag-ecmp-understanding.html
Standard hashing is on payload it seems,mall the iperf packets might have the same payload, so they end up on 1 of the members of the link..
Change to level 2 info, your clients have different mac adresses. -
I see more info on hashing here: https://forums.juniper.net/t5/Ethernet-Switching/EX2200-LACP-hashing-algorithm/td-p/107844
I don't see any issue with LACP. I'm expecting it to only do one gigabit links for four separate clients. I think it's strange that I need more than one stream of iperf to saturate the line. In my tests on the management interface, I plugged a linux machine directly into the management port. No switch involved.
Any idea why iperf needs -P 32 or 32 Streams to saturate the line?

What OS are the client pc's running ?
It might be the iperf clients for the OS version issues.My test from pc with windows 7 to freebsd 10.1 server was 350 MB/sec with one session in iperf.
It also depends on buffer size, packet size tested etc, i think.This was with 10GE link over intel cards.
Wintel combination did not want to go faster than that it seems.Freebsd to freebsd was simply close to line rate with one session.

line as an example here showing then up as 4 GBit/s aggregated.I think it's strange that I need more than one stream of iperf to saturate the line.
How much you will need to saturate one single line?
In my tests on the management interface, I plugged a linux machine directly into the management port. No switch involved.
And no LAG, VLAN and QoS over all or?
Any idea why iperf needs -P 32 or 32 Streams to saturate the line?
Each line has its speed limit but this is mostly also owed to other circumstances besides.
Link-level type: Ethernet, MTU: 1514, Speed: 4Gbps, BPDU Error: None, MAC-REWRITE Error:1.- What is the MTU size on all devices in that test?
2.- What does you configure the LAG?
– (2 Lines sending and 2 lines receiving or 4 lines sending and receiving)
-- (active / active all lines are in usage or active passive one line is in usage and the rest is as spare for failover)In normal you will have no need for that experiences to go with your set up.
You can do the following things in my eyes.
1.- Setting up a static (manual) LAG and use round robin method and on top 2 line for sending and 2 lines
for receiving by using active / active
2.- You could use your Layer3 switch to route between the VLANs only inside of that switch that will be
more nearly wire speed and the freed capacities from the pfSense box you will be perhaps able to use for
other things, or as a silent reserve. -

It looks like "-P 2" will saturate the line, but "-P 1" will not.

Correct. The management port does not have any LAGG, VLAN or any other tags. Just one computer plugged directly into the pfsense machine.

MTU on Juniper switch is 1514.
MTU on linux clients are 1500.
MTU on pfsense LAGG is 1500.
MTU on pfsense igb0 / igb1 / igb2 / igb3 are each 1500
Detailed ifconfig is belowTo answer #2
LAGG is configured as LACP over 4 lines. Each of the 4 lines both send and receive. If one line goes down, Juniper will ignore it and then use the remaining acceptable lines. Only one line is necessary to maintain satisfactory connection.ifconfig on pfsense: THIS IS THE LAGG lagg0: flags=8843 <up,broadcast,running,simplex,multicast>metric 0 mtu 1500 options=400bb <rxcsum,txcsum,vlan_mtu,vlan_hwtagging,jumbo_mtu,vlan_hwcsum,vlan_hwtso>ether XX:XX:XX:XX:XX:XX inet6 XXXXXXXXXXXXX%lagg0 prefixlen 64 scopeid 0xb inet 192.168.10.1 netmask 0xffffff00 broadcast 192.168.10.255 inet 10.10.10.1 netmask 0xffffffff broadcast 10.10.10.1 nd6 options=21 <performnud,auto_linklocal>media: Ethernet autoselect status: active laggproto lacp lagghash l2,l3,l4 laggport: igb0 flags=1c <active,collecting,distributing>laggport: igb1 flags=1c <active,collecting,distributing>laggport: igb2 flags=1c <active,collecting,distributing>laggport: igb3 flags=1c <active,collecting,distributing>THIS IS MANAGEMENT PORT em1: flags=8843 <up,broadcast,running,simplex,multicast>metric 0 mtu 1500 options=4009b <rxcsum,txcsum,vlan_mtu,vlan_hwtagging,vlan_hwcsum,vlan_hwtso>ether XXXXXXXXXXXX inet6 XXXXXXXXXXXX%em1 prefixlen 64 scopeid 0x2 inet 192.168.5.1 netmask 0xffffff00 broadcast 192.168.5.255 nd6 options=21 <performnud,auto_linklocal>media: Ethernet autoselect status: no carrier THIS IS ONE OF THE PORTS INCLUDED IN THE LAGG igb0: flags=8843 <up,broadcast,running,simplex,multicast>metric 0 mtu 1500 options=400bb <rxcsum,txcsum,vlan_mtu,vlan_hwtagging,jumbo_mtu,vlan_hwcsum,vlan_hwtso>ether XXXXXXXXXXXX nd6 options=21 <performnud,auto_linklocal>media: Ethernet autoselect (1000baseT <full-duplex>) status: active</full-duplex></performnud,auto_linklocal></rxcsum,txcsum,vlan_mtu,vlan_hwtagging,jumbo_mtu,vlan_hwcsum,vlan_hwtso></up,broadcast,running,simplex,multicast></performnud,auto_linklocal></rxcsum,txcsum,vlan_mtu,vlan_hwtagging,vlan_hwcsum,vlan_hwtso></up,broadcast,running,simplex,multicast></active,collecting,distributing></active,collecting,distributing></active,collecting,distributing></active,collecting,distributing></performnud,auto_linklocal></rxcsum,txcsum,vlan_mtu,vlan_hwtagging,jumbo_mtu,vlan_hwcsum,vlan_hwtso></up,broadcast,running,simplex,multicast>
