howto reduce the ping?

[Julius Junghans <julius.junghans@xxxxxx>]

Hi,

with the attached config my gaming ping is still +20ms, even if the line isn't  
saturated..can anybody give me a hint how to get a better response time? 
my line: 1024/128kbit

outbound:
one htb qdisc for gaming (7kbps) prio 0 ceil 14kbps<- should get more traffic 
when needed. 
Htb again for irc and default.


inbound:
css, irc, p2p, default <- same shema as before, give css enough bandwith and 
allocate the rest for the other classes.

Are packets in 1:10 (css) are transfered as fast as they arrive?


 

Same config without line breaks:
