optimization

I have a HTTP server that serves only two kinds of page: about 10 KB and about 16 KB (both compressed, other files are from CDN). As the latency is quite high (ping takes more than 300 ms), I want to optimize the TCP stack so that client receives the whole page ASAP.

Thus, I have a double question:

Which parameter do I have to change (which value of TCP window)?
How to change in (a Debian box, and FYI, there is a Varnish before the HTTP server).
