Hello, I am running squid-2.7.STABLE7 and we are experiencing poor performance (very slow page loads, timeouts etc.). This is in a large campus setting with a few thousand users. One observation is that the elapsed time for HTTPS CONNECT operations looks like below. Are these numbers normal, or too high? Over longer durations, I find many values clustered around 60000, 120000, 240000 etc., which makes me suspect timeouts. The elapsed times for GET and POST are better.
For example $ sudo tail -f /var/log/squid/access.log | grep CONNECT 1313146579.775 215331 10.91.0.31 TCP_MISS/200 27133 CONNECT s.yimg.com:443 - DIRECT/118.214.109.227 - 1313146579.775 215346 10.91.0.31 TCP_MISS/200 34679 CONNECT s.yimg.com:443 - DIRECT/118.214.109.227 - 1313146579.983 173857 10.91.0.31 TCP_MISS/200 281027 CONNECT fbcdn-sphotos-a.akamaihd.net:443 - DIRECT/204.2.171.153 - 1313146580.555 9250 10.91.0.34 TCP_MISS/200 2992 CONNECT in.data.toolbar.yahoo.com:443 - DIRECT/98.137.53.23 - 1313146580.584 338494 10.91.0.31 TCP_MISS/200 9960 CONNECT accounts.youtube.com:443 - DIRECT/74.125.236.43 - 1313146580.620 338530 10.91.0.31 TCP_MISS/200 2655 CONNECT ssl.google-analytics.com:443 - DIRECT/74.125.236.62 - 1313146580.650 6867 10.91.0.34 TCP_MISS/200 7611 CONNECT login.yahoo.com:443 - DIRECT/202.86.7.110 - 1313146580.806 208366 10.91.0.31 TCP_MISS/200 7532 CONNECT ak1s.abmr.net:443 - DIRECT/173.222.9.8 - 1313146581.534 7853 10.91.0.33 TCP_MISS/200 5963 CONNECT login.yahoo.com:443 - DIRECT/202.86.7.110 - 1313146581.626 11838 10.91.0.32 TCP_MISS/200 3552 CONNECT in.data.toolbar.yahoo.com:443 - DIRECT/98.137.53.23 - 1313146581.855 14871 10.91.0.33 TCP_MISS/200 45503 CONNECT www.facebook.com:443 - DIRECT/69.171.228.11 - 1313146581.892 12052 10.91.0.33 TCP_MISS/200 18001 CONNECT fbcdn-photos-a.akamaihd.net:443 - DIRECT/69.31.33.49 - 1313146581.939 10247 10.91.0.33 TCP_MISS/200 17345 CONNECT fbcdn-photos-a.akamaihd.net:443 - DIRECT/69.31.33.49 - 1313146582.177 13371 10.91.0.33 TCP_MISS/200 13324 CONNECT fbcdn-photos-a.akamaihd.net:443 - DIRECT/69.31.33.49 - 1313146582.178 12442 10.91.0.33 TCP_MISS/200 13260 CONNECT fbcdn-photos-a.akamaihd.net:443 - DIRECT/69.31.33.25 - and the following commands: $ sudo tail -n 100000 /var/log/squid/access.log | awk '/GET/ {total +=$2; c += 1}END{print c, total/c }' 89789 3819.93 $ sudo tail -n 100000 /var/log/squid/access.log | awk '/POST/ {total+= $2; c += 1}END{print c, total/c }' 5373 3318.82 $ sudo tail -n 100000 /var/log/squid/access.log | awk '/CONNECT/{total += $2; c += 1}END{print c, total/c }' 4640 81533.5 As you can see, the elapsed time for CONNECT (~81s average) is far higher than the others (about 3-4s average). Is this just due to connections being kept alive, or is there something else likely wrong? Also, do the average numbers for the others look normal or are they too high? Thanks, Nitin Chandrachoodan
