[squid-users] slow response for cached objects

Hi,

Sometimes I see squid is taking time in delivering contents even if
object is available in its cache. Any idea what could be the reason?
I used external url rewrite program to strip the query string. Is it
slowing down serving process ?

First 2 line shows squid took 703 milliseconds to deliver the contents
and rest of the url shows 0 milliseconds

Following is rewrite url helper program I use which was sent by Henrik
and I have modified it bit to strip the query string.

#!/usr/bin/perl -an
BEGIN { $|=1; }
$id = $F[0];
       $id =~ s/\?.*//;
       print "$id\n";
       next;
