Re: Performance question

Hi ,

I am using Squid 2.1Patch3 on Solaris 7.0/X86 with
PII450 512MB - 2 CPU
RAM-256 MB , 2 7500 RPM SCSI II HDD- 4 GB each.

I am using Polygraph 1.0p7 with(patch) but squid not
able to handle more than 75/req sec. ( --dhr 55% and
--rep_cachable 80p same as bakeof)
I have tuned TCP( Solaris 7.0) for following
parameter...

tcp_time_wait_interval 60000
tcp_conn_req_max_q 16384
tcp_conn_req_max_q 16384
tcp_recv_hiwat_minmss 24

FD is set to 12288.

Even by increasing RAM up to 1 GB , I don't find any
improvement in performance.

I get the following error in my cache.log file

1999/06/04 13:53:55| comm_write: fd_table[906].rwstate

I have changed the NUMTHREADS 128 in ...src/aiops.c
....

Polygraph server can handle 500 req/sec without proxy
for an hour.

Any help will be greatly appreciated.....
