Re: [squid-users] tweeking squid for vsats

I want to bring your notice that setting you are going to tell Mr Rahul are
by default set into Linux like show below..

1) be sure that the followings are enabled in your /etc/sysctl.conf:

    net.ipv4.tcp_window_scaling=1
    net.ipv4.tcp_timestamps=1
    net.ipv4.tcp_sack=1

so no need to change these setting.... better to check again your upstream
and downstream packet delay...first

| the latency is caused by the speed of light and cant be decreased it...

links),

|
| here are my recommendations to improve your service:
|
| 1) be sure that the followings are enabled in your /etc/sysctl.conf:
|
|     net.ipv4.tcp_window_scaling=1
|     net.ipv4.tcp_timestamps=1
|     net.ipv4.tcp_sack=1
|
| 2) increase your tcp window size according to bandwidth-delay product
|
| 3) parent your squid to your "isp net" proxy server
