Very slow internet browsing
-
I have narrowed my issues down to just IPv6 I believe.
My IPv4 gateway appears to keep a solid connection with a ~10ms latency, however my IPv6 gateway varies from 10ms - 250ms. Any ideas what could have caused this issue with the most recent patch?
Prior to the patch I did not have this issue.
-
Another user reported similar symptoms when using Intel NICs and some tweaks applied. Are any of you running similar setups?

I do not know what network cards I have
But I know that I did not changed their settingsIs there a command that

Is there a command that
Show me the computer's hardwarepciconf -lvIt won't spell out the nic brand or model, you'll probably need to Google the chip number.
You can also look at this file to get the driver version, but that won't list the specific nic model:
/var/log/dmesg.boot -
Well if you haven't added any tweaks in loader.conf.local (for which you'd have to know what hardware you're running) then this is a different problem. Or at least a different solution.
You can tell what NICs you have by what drivers are attached to them. Intel NICs will usually use the em or igb drivers so your interfaces will be em0, em1 etc. Beyond that you need the PCI info for more detail but here the drivers are enough.Steve

Is there a way to know if Intel cards have a problem with pfsense
With the latest version Anyhow
-
Just to clarify this, there is not any known bug in the Intel driver or card setup (that I know about at least). I mentioned this only because the symptoms described were very similar to those I had been reading about in another thread.
https://forum.pfsense.org/index.php?topic=74942.0
In that instance the high latency was seemingly solved by removing the loader.conf.local setting limiting igb to 1 queue.
Steve
-
I know I understood it the first time
My questions were just to rule out a network card problemWhat could it be
why is the latency go crazy
from 10 to 300
why all internet browsing so slow
Except from the upgrades i did not changed anything -
OK. I just wanted to be sure I hadn't mislead anyone.
Your interfaces all appear to be older cards, 2 fxp NICs and one dc. Are you seeing latency problems across all of them?
The driver changes I was talking about were for the newer Intel drivers (em. igb, ixgb) for gigabit NICs and they went into 2.1.1. I don't beleive there were any driver changes between 2.1.1 and 2.1.2.The temperature of the CPU is also higher than normal
This would indicate that the CPU is working hard on something which could be causing the latency. What do you see if you run 'top -SH'?

A couple of things that have caused similar symptoms in the past come to mind. If you have any sort of CPU frequency scaling enabled and it's not quick enough responding to the load it cam start to appear like a large load. Doesn't really explain why it's running hot though.
The other thing is ASPM which can cause problems similar to this. Not sure if that's PCIe only though. Worth checking if it's an option in your BIOS and disabling it if it's there.Steve

pciconf -lvIt won't spell out the nic brand or model, you'll probably need to Google the chip number.
I always add the file that pciconf can use to translate device ids to descriptive device names on all my pfsense installs so that the list is much easier to read. I really wish pfsense would include that file by default. It is very useful but it is about 400 KBytes.
/usr/share/misc/pci_vendors
I just do a search for that file for whatever version of freebsd pfsense is running and manually put it in place. pciconf is so much easier to read after that.

If it were a hardware problem I would expect to see a load of errors in Ststus: Interfaces:
You aren't seeing a high interrupt load then if you run 'top -SH' at the console (or via ssh)?

What came out of this command
I posted earlier post -
If you look at my output from top -SH above I have an extra line the breaks down the usage by type. If you run it fro the console, rather then via the webgui, and allow it to go a few cycles you'll see that. It probably doesn't contain anything useful but at this point it's worth checking anything. :)

Nothing much there.
Kind of out of ideas here but I did notice that you are using some swap. That can cause serious performance issues. I wonder if a Snort rule update has pushed you over the limit of RAM and started swapping. Check your memory RRD graph to see if ran out of free memory at any point.Steve
