Optimum Minrate/Maxrate For My server

[kamale]

Was wondering if any1 knew what would be the most optimum minrate/maxrate and tickrate for my server. My stats r below.
Some people say i'm able to support up to 32 or more players. I did run once smoothly with 20 players with 100 tick but somehow it suddenly started to lag up for no reason.

OS: Ubuntu x64
2.4ghz Duo core
4GB DDR2 667mhz
Cable connection running at 100mb/s download and 3mb/s upload.

Currently these are my settings. But they seem to lag up a lil once in awhile.
// bandwidth rates/settings
sv_minrate 0
sv_maxrate 0
decalfrequency 10
sv_maxupdaterate 101
sv_minupdaterate 10

Also is there a way to increase my sending bandwidth of file or maps? Any other information to keep my server running at optimum effeciency will be greatly appreciated thanks again guys

Well as for tickrate, dont set a server above 18 slots to 100 tickrate. Also is it dual core 2.4, or dual 1.2 ghz?

My duo core is 2.4ghz each.
