CS: S Server Lag at Round Start Only + Choke

[scso1502]

Hey guys, Below are my configs. Can someone knowledgable please check them and make sure I'm on track with these settings. These are what I'm using for 100-Tick 500 FPS Windows 2003 Public Servers on my dedicated boxes and players are getting choke up to 45 with 20 players in a GunGame/Deathmatch server. When people use their Mics, it goes even higher. The problem is the same for all the servers on the box, including regular Valve Maps. It's especially pronounced at round start and when more than 10 are playing on the servers.

HELP!!!! THANKS IN ADVANCE!

Command line:

-game cstrike +fps_max 600 -console -tickrate 100 +ip xxx.xxx.xxx.xxx -port 27015 +maxplayers 24 +map de_dust2
