Hi everyone,<br><br>Can anyone give some tips on how to diagnose the sources of bufferbloat? According to the Netalyzr test at <a href="http://netalyzr.icsi.berkeley.edu/">http://netalyzr.icsi.berkeley.edu/</a>, I have 550ms of upload bufferbloat. I tried all kinds of stuff on my Windows 7 laptop:<br>
<br>- For the Intel(R) 82567LF Gigabit Network Connection, I put receive and transmit buffers to the lowest value of 80 (80 bytes? 80 packets? I don't know). I also disabled interrupt moderation. <br>Result? Still 550ms.<br>
- Then I connected my laptop directly to my cable modem, bypassing my Mikrotik 450G router. Result? Still 550ms of bufferbloat. <br>- Then I put a 100 megabit switch between the cable modem an the laptop (as both cable modem and Intel NIC are gigabit). Result? Still 550ms of upload bufferbloat.<br>
<br>I'm out of ideas now. It seems I can't do anything at all to lower bufferbloat. Or the Netalyzr test is broken?:-)<br><br>many thanks for your advice,<br>Jeroen<br><br>
