Gr8 ..:D.After doing this the cpu utilization has come down to around
3% to 4%. even my Number of clients accessing cache: reached 1567
in no time and was still incerasing but Like Tek Bahadur said i ran
out of file descriptors :(. So i ll now recompile squid the way i just
saw on one of the mailing list and let you guys know what happened.

But the issue is my bl-porn.conf has only 3214 lines and i really need
them. Is there any other way i can do it without stressing the CPU ?

>>could you show the output of these commands?

>>unset http_proxy
>>time wget http://www.us.kernel.org/pub/linux/kernel/v2.6/linux-2.6.9.tar.gz
>>time wget http://www.in.kernel.org/pub/linux/kernel/v2.6/linux-2.6.9.tar.gz

Well i do not have wget installed on my proxy so i did a `ssh -D 1080
xxx@xxx -fN` from one of my servers . i had squid shutdown coz it was
giving a lot of warnings . This is what i get when i wget a file

48.8 Mb in 7min 46 sec --- from India (.83 Mbps)
48.8 Mb in 18min 47 sec ---- from US (.34 Mbps)

So on a 4
