need for tcp fine-tuning on heavily used proxy server
- by Vijay Gharge
Hi all,
I am using squid like Internet proxy server on RHEL 4 update 6 & 8 with quite heavy load i.e. 8k established connections during peak hour. Without depending much on application provider's expertise I want to achieve maximum o/p from linux. W.r.t. that I have certain questions as following:
How to find out if there is scope for further tcp fine-tuning (without exhausting available resources) as the benchmark values given by vendor looks poor! Is there any parameter value that is available from OS / network stack that will show me the results.
If at all there is scope, how shall I identify & configure OS tcp stack parameters i.e. using sysctl or any specific parameter
Post tuning how shall I clearly measure performance enhancement / degradation ?
