Hi, i have server from ovh.

CPU: Intel Xeon E5-1650
Cores/threads: 6/12t
Frequency/burst: 3,2 GHz/3,8 GHz
Intel Smart Cache: 10 MB
RAM: 64 GB DDR3 ECC 1333MHz
Disks: 2x 2 TB SATA3
RAID: SOFT
Bandwidth: 500 Mbps
Traffic: Unlimited

I run

2 x 14 slots [128 Tick]
3 x 20 slots [128 Tick]

I tried normal kernel + 1000hz kernel both didn't help me.

Choke is in range 5 - 30%.

maxrate 0
minrate 128000
minupdaterate 128
maxupdaterate 128
mincmdrate 128
maxcmdrate 128


For me on server with this specs its impossible to have choke like this. Maybe you will know what's going on. Thanks in advance guys. Regards.

Swapmemory disabled?
What is renice for the servers? Renice = priority tasks
Try renice -19 and disable swapmemory if did not yet.

Are you 100% sure that your cpu is scaling properly? https://code.google.com/p/i7z/ << You can use this to check.
Frequency scaling is enabled by default in debian. Scrds for some reason dosn't work well with it. Cause of that cpu only ran @ half speed.

@veli @oalaro

2 screens for you guys:

http://scr.hu/1rbb/dxydm
http://scr.hu/1rbb/ndam0

@veli

As you can see on second ss there is swap so like you said i need to disable it, right?
I never used renice.

EDIT: I disabled swapmemory + used renice -19 , unfortunetelly nothing help.

@oalaro

As you can see on first ss cpu frequency scaling is good.

@everyone

Sv / var would generally spike if it was cpu related.

Can OP confirm if only choke spikes while holding a stable sv / var?

What connection do you have and what are the rate settings for one of the 20 slot servers that chokes?

Maybe your network cvars in Server.cfg can help. Engine seems oke .

Thats from net_showsplits 1 , maybe you can read something from it.

I found solution for my problem and i'm glad to share it with you guys.

Code:
sv_minrate 128000 
sv_maxrate 0 
net_splitpacket_maxrate 128000 
net_splitrate 2 
sv_mincmdrate 128
sv_minupdaterate 128
net_maxcleartime 0.01 
sv_force_transmit_players 0 

sm_cvar sv_parallel_sendsnapshot 1 
sm_cvar sv_enable_delta_packing 1 
sm_cvar sv_maxunlag 0.1 
sm_cvar net_maxcleartime 0.001 
sm_cvar net_minroutable 1000 
sm_cvar net_earliertempents 1 

sm_cvar sv_parallel_packentities 1 
sm_cvar net_compresspackets 0 
sm_cvar sv_multiplayer_maxtempentities 1
I just paste that and it works.
