hi, all we r using squid 2.6.12 for months. recently when we parsing squid access log and studying on the value of "serveing time", we fount it to be interesting that many slow serving actions is finished within 120 seconds or 60 seconds. it seems like that there is a machanism inside squid to ensure that all content can be server in a certain threshhold time, say 120s or 60s. or at least there is a timeout setting or configuratioin. a few sample data as following: -content----- process time(s)----- xx.js 119.931 xx.jpg 119.813 xx.gif 120.133 xx.gif 59.92 xx.png 119.239 i strongly feel that the time figure indicated something. meanwhile, the load on squid box is pretty low(usually under 1), and requests/second is aroun 100/s. anybody have met same problem? any good suggestions? appreciated. thanks.
