Tickrate problems?
#1
I have some problems on my warserver with the tickrate. Normally, the tickrate should be steady at 100, but mine isn't steady. When you do something in the server (throw a HE grenade or flashbang) the tickrate drops below 90 (sometimes 80, sometimes 85).

The gameserver is hosted on my dedicated server (Dell PE 1850) with a Dual Xeon 2,8Ghz processor, 4GB DDR memory and a 73GB large hard-disk (SATA). The operating system that is used is Debian (newest version). All this should be fast enough (I'm not running anything else). The only plugin on the gameserver is zBlock, which is required in all known leagues.

- I have tried to reboot the gameserver, also the dedicated server itself.
- Used several configs (ESL, CAL, ClanBase)
- Tried different command lines

What should I do to make a stable tickrate 100 server?

so on your netgraph, its the inbound or outbound that drops?

also whats your fps at?

do a rcon stats a bunch of times and copy and paste here

It's not my own computer that is lagging, it's the inbound that drops (of course, lol).
I tried +fps_max 600 and +fps_max 1000, both with the same result.

Another drop, the FPS seems to be 83, why is that so?

well your fps is dropping causing your tickrate to go with it.
maybe your cpu cant hang. I dont know much about xeons, but i do know that the older p4 based architecture isnt very good for srcds. Maybe someone else can verify that.

i would try making your own kernel. strip everything out of it that you dont need. granted if youve never done this before its a little daunting but for best performance id recommend it.

That's not really an option, because the (dedicated) server is located 200 miles away from my home.
I'm sure the Dual Xeon 2,8Ghz is able to run about 5 or 6 srcds servers.

you can update your kernel remotely, you don't have to be at the machine to do it. if you are using fps_max 500 and it's stuck at 250 then you will need to recompile it to get 500fps (if that's what you want).

do a ps aux and see what is running on that machine, there's prob a lot of stuff you don't need.

looks ok unless some things scrolled off the screen, how about uname -r for your kernel version?

Code:

I have Debian (newest version, I think).

the issue is your fps drop below 100 and your fps must stay higher than your tickrate to sustain it.

you def need a kernel rebuild done to maximize your fps.

if your not comfortable doing it, then try to find someone who is.
