Reducing Lag Spikes?

[jameshaigh]

Hey,

First off, I'll tell you about my deicated server, so you know the scenario:

Intel Pentium 4 @ 2.66Ghz
1GB RAM
160GB Hard Disk
Upto 10mbps pipe
Debian Etch

No other services running except lighttpd.

Server Type: Counter-Strike: Source, 40Players and 66 tickrate.
Plugins: metamod, mani 1.2B, mattie event scripts, noblock, CSSDM, time_left


The problem I'm having is that when 3 or more people use their microphone at once, the server lags REALLY bad.
Generally it runs fairly smooth, with small lag spikes occuring occasionally.

When around 30 people are on, the server is uploading around 2.5mbps, if that's any help.

My autoexec.cfg:

Code:

mani_reverse_admin_flags 0 // Set the option to reverse the meaning of the admin flags set in adminlist.txt
mani_reverse_immunity_flags 0 // Set the option to reverse the meaning of the immunity flags set in immunitylist.txt
mp_dynamicpricing 0
mp_roundtime 9
mp_freezetime 0
mp_timelimit 30
sv_minrate 4000
sv_maxrate 32000
decalfrequency 60
sv_maxupdaterate 67
sv_minupdaterate 30
es_load examples/auth/basic_auth
es_set BASIC_AUTH_ADMIN_LIST "STEAM_0:1:0000000"
es_load event_map_end
es_load time_left
es_load noblock

..and my server.cfg:

Code:

hostname "DEATHMATCH SURF | Nitrous 40 | NOBLOCK + FASTDOWN"
rcon_password *******
mp_fraglimit 100
mp_timelimit 30
mp_buytime 9999
sv_consistency 0
phys_pushscale 3000
sv_airaccelerate 2000
mp_roundtime 9
mp_freezetime 0
sv_downloadurl "http://72.18.206.28/*********"
sv_alltalk 1
sv_pure 0
exec mani_server.cfg

Could someone tell me where I'm going wrong, and possible ways to fix this?


Thanks very much!

James.

Our hlds server is using about 200 KBytes/s upstream with 30 players same as our srcds server and they run at max rates.
Its about 700GB traffic/month for one 30 player server if its almost full all the time.
If you disable ingame voice on your server are you then experience any lag ?

[jameshaigh]

Only very little. I really don't want to disable ingame voice (although I've had to once or twice while I was in-game) because it's a large part of my server. My "regulars" (lol?) always use their mics and love it, it's a great way to make new friends.

Is there a lower quality microphone setting? Like in teamspeak? I'm not too sure there is, but will that help?

There are a few codecs available, there has been a new one lately set to default called sweex. This one should have about the same quality but less bandwidth. Try to add this in the server.cfg:

Code:

sv_voicecodec voice_speex      //Set the voice codec
sv_voicequality 2      //Quality of voice, 1-5 where 1 is worst and 5 is best. 1 uses least bandwidth, 5 uses most

Also on a side note, every server above 32 players should be 33 tick, most likely will take away some lag too if you set that.

<19 = 100 tick max
<32 = 66 tick max
>32 = 33 tick max

<19 = 100 tick max

Thanks for your help. I've changed the codec to voice_speex and quality to 2. Also changed the tickrate to 33.

Thanks for your help.
