RV: LATENCY PROBLEMS

Linux Advanced Routing and Traffic Control

Hello there, 
   I'm having lots of problems with my setup here. Let me explain:

I am network administrator for my university dorm. We are about 300 users,
and we have 2 ADSL connections doing load balancing with 300kbits upstream
and 2Mbit downstream. 

The load balancing is working great, we are doing connection tracking so I
can mark and hence prioritize interactive traffic and ACKS on the upstream,
and with ipp2p I mark p2p traffic allocating it under the non-interactive
queue.

The problem comes when there is more than 70 users + or -, when interactive
traffic stops working at all, or it has a very VERY high latency.

I have a setup based on HTB and WRR. 

I have only two possible explanations, or either the CONNMARK module
introduces a very high latency when the number of entries on
/pron/net/ip_conntrack rises above lets say 800, or maybe the Ethernets I
have (cheap Ethernets) are getting saturated with that amount of traffic.

My server is a AMD Duron 800MHz with 768Mb of RAM.

Anyone knowing the marvellous solution? :)

		Thank you guys..
