Re: Similtaneous connections

Hi!

Depending on what OS you are running sometimes you need to optimize the
TCP-configuration.
We use linux here and when we started using squid it also slowed down
during peak hours.
If you're using linux, take a look at:

/proc/sys/net/ipv4/
                tcp_fin_timeout - I lowered this setting to 30
                tcp_max_syn_backlog - Increased to 512
                tcp_keepalive_time - Set to 7200 (default?)

With these settings it runs very smooth .. during peak hours we have 14-16
Requests / sec with ~3000 clients running. Our cache is 14GB.
