c6300 Bufferbloat issues
Hey All, So I ran this speed test on my cable connection. I have great results, with the exception of my F in bufferbloat. How do I resolve this bufferbloat issue. The information on DSLReports s...
I work from home and do VOIP and screensharing sessions over GoToMeeting frequently. I have been experience major slowdown issues during these sessions. The most recent time this happened no one else is in the house or using the network. I am trying to rule out everything that could be causing it and this buffer bloat issue is on the list.
That would be really frustrating. I'm not sure, though, what you mean by major slowdowns: what do you see? (slow downloads, lag in responses, ?)
It seems to slow my entire system down to a crawl. Which doesn't seem to point towards a network issue, but my performance counters are not spiking. My CPU utlization is usually around 60% and memory is around the same and I have an SSD which is barely being used at the time.
This is only an issue when I am doing a screen share session. I have had similar issues with sharing over Lync, which is now Skype for Business.
PC Stats:
Intel i7-5600U CPU 2.6GHZ
16GB Ram
500GB SSD
As soon as I stop sharing my screen everything goes back to normal. So I am wondering if this is a bad response by my sharing applications to the buffer bloat issue.
DarrenM What other buffer bloat evaluation tools would you recommend? I have run it from multiple browsers and with "Private" as well as without. I always receive an F on bufferbloat.
Oops. The forum system misfired. Check my next message.

>>> Is it slow to open applications/windows? Does other network interaction (what kind) get slow?

>>> My next recommendation would be to see what happens to your computer while stressing the network in each direction:
1) In the Command Prompt window, ping google.com - use ping google.com -n 1000 so that it keeps going
2) For the download test, start downloading a big file from your favorite site
3) Notice a) what happens to the ping times? Does the computer slow to a crawl?
4) For the upload test, stop the download, and upload something. The easiest thing is uploading a video to Youtube.
5) Notice the same things as 3) above.
6) I'd like to know what you find.
NB: This is another form of bufferbloat testing: it is measuring ping times during download or upload.

The mouse jumps around the screen and takes a very long time to respond to clicks between browser tabs or different windows. Scrolling takes about 10 seconds to scroll 1 line in a browser window even if the page was already loaded. And you can forget about launching new applications even lightweight ones like notepad.

Started the ping test and was consistently getting 20-40ms response times.
Started to DL a 20gig file from my cloud hosted sharepoint site and pings grew to mostly 100-300ms occasionally a 30-99ms would sneak in as well.
Cancelled the DL and immediately back to 20-40ms response times.
