Intel DN2800mt x64 2.0.3-2.1 bandwidth
-
I've seen +900Mbps through my DN2800MT as well.
Seems surprisingly high for an Atom board. You do anything special? It that actually through?

I think he is saying the NIC is capable… Well - Shall see.
-
Nope, still pretty slow although it did pick up a little more speed. 328Mbps TCP and 503Mbps UDP
I'm looking at the system activity and what I thought was 87% cpu utilization is actually 87% cpu0 (Idle) WTF!!! so its utilizing 13%
Kernal em1 que and kernel em2 que shows 5.8%
-
I'm thinking firewall will only utilize one core (or thread) fully.
So, can you turn off hyper-threading in bios (if its present) and try again… This time looking at per-core utilization.
Its just a theory.
-
I did that from the get go.. standard practice minimizing latency. Hyperthreading is off.. right now as we speak I have both tcp offload engine off, "tried with it on as well"
232Mbps

Really? Hmmmm…
Its good to know all my theories are not off the wall then.Question - How long is this test you run?
Is it long enough to see if HDD is involved in the process?(CPU is largely idle. Its got me looking elsewhere. PCIe is plenty fast)
-
it runs indefinitely until I disconnect.. I'll have my SSD tomorrow, im not sure thought that its touching anything on the HD
-
I'm not sure that it is. Also not sure it isn't. Firewall gets logged. States get logged. There is squid… I'm just interested to see what it would do with SSD. Speaking of SSD, what kind?
-
lemme run downstairs and try swapping cables..
-
cable change did nothing. its a 32Gig Samsung Full height mSata.. rated 520MB/s, I think the 32 gig is a 4channel though so it will probably be around 320MB/s.. I put it on a compeletly separate gig switch too…. I'm gonna put both these computers on the same switch and see if I get the bandwidth i'm looking for.
-
Yep - Being on same physical switch might speed things along. Its a good switch?
-
yep Enterasys b3g124-48.. and yes maxed out the lan link. this is frustrating
-
That is really too nice a rig for a home play toy…
I just picked up a HP V1910-24G 24 port for $30 and I was jumping with joy...
I'm easily happy...
-
My next question might be stupid, so feel free to call me an idiot for asking…
You have no slow painful packages like snort running? No traffic shapers running anywhere?
(asking dumb questions is part of my brainstorming process)

I found mine on a ebay ad from someone "junking a old business" HAHHAAHAH.. 100 bux shipped. I snatched with the quickness. Of course overkill is always nice.
nope, fresh installation no packages
-
im gonna try reinstalling, not that it would make a difference, perhaps something got screwed up. be back in a few.
-
I found two references to check…
1. reviewing you dmesg output that you have no other device using one of the nic's irqs
2. Try with system > advanced > polling on.
Might as well try before a reinstall....
-
how would I go about checking irq
in bios I have everything extra disabled.
-
ok weird thing, reinstalled cpu0 is showing idle 24% and 11% under load. while cpu1 is sitting 88.77%idle.
could it be misrepresenting cpu idle state after updates? poll is enabled.. sitting 100% idle, or is it the Polling eating cpu? I get same throughput.
also going over dmesg list, Looks like my nic uses irq 17 and 18. 18 is also shared with USB controller.. Let me try disabling all usb no terminal
Just tried changing tool to iperf and netted 193Mbit and 191Mbit on default test. this isn't right. I can't for the life of me figure out why it doesn't saturate cpu or nic. just a little more information. when I run iperf or tamosoft tools, I can still pull 55Mb from my isp. the cpu gets further away from idle when I do. so I dont' know anymore. time for sleep.
-
Are you running 'top -SH' to show all system processes etc?
If you try polling, it's not recommended, make sure it correctly stops polling when you disable it again. I found it sometimes gets 'stuck'. Reboot.
You could try enabling IP fast forwarding in System: Advanced: System Tunables: That usually speeds things up when routing but breaks IPSec so no good if you need that.
