Very slow internet browsing
-
I also noticed that my firewall is doing horrible sync time. Notice the very high jitter and high offset. Considering two of my peers are local with sub ms latency I should not have that high of jitter or offset.

Dude, this thread is about "slow internet browsing", so unless you "browse" internet via NTP, create your own thread.

I too didn't see anything in the logs that would explain the high latencies. Tried a few things such as going through some options and clicking on save to see if anything would pop up an error to indicate a configuration conflict.
After 3 reboots it finally became stable and latency issue went away. It's not as low as it was before but certainly alot better than it was.
I checked my work firewall that we use for the wireless connections and it didn't show the same behavior. Then again that firewall is basic without any of the extra packages installed.
Maybe one or more of the packages are conflicting? I even tried re-installing all the packages.
Right now it's working ok. So I don't know if just a fluke with the timing of the upgrade and maybe Comcast issues?

Whoa ease up. 1 I have already posted to this thread about my issues. 2. My ntp info is to help point to what may be the issue. Ntp issue like this are normally due to the ntp process not getting enough cpu time.
-
The issues I was experiencing this morning and last night was probably caused by Comcast. Going through the graphs with a fine comb the issues didn't start until at around 8pm last night and finally got resolved at around 3pm today. Right after the update Thursday night the graphs showed normal activity until last night. Now the graphs have returned to normal.
So I don't think PfSense upgrade had anything to do with this, least in my case.
Just bad timing.

Good Morning {in my area}
Now Morning
And out of 10 computers are connected and surf them {brothers sisters parents}
Only my computer works now
And the graph shows a lot of connectionsbrowser Open with two tabs
One of the dashboard
Second of this page with the messageI guess there is a log in which all registered
Where can I see it. -
Addition
Now I checked the Internet link with Mlab Shaperprobehttp://www.measurementlab.net/tools/shaperprobe
Although the dashboard
Says there are no packet loss
The test stops in the middle
And gives a message"measurement aborted due High packet loss rate"

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?

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

Possibly not 100% correct, but the nics might be these:

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.

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
