hlds become stable FPS ???

[christophf]

Hi all,

I'm new here and would like to introduce myself. Im concerned already for a very long time with the topic Kernel Optimatizion etc.
My resualts are, that my Server got very stable FPS without some libhacks etc.
But, not absoulutely stable. So now i hope u can help me to fix my problem to get 100% 1000FPS.

I add a picture from my server

Edit: using Realtime Kernel with realtime processing on hlds and on timers (softirq-hrtimer)

[doggy93]

Try the Idler, also from the Kernel Optimization site.

[christophf]

the ilder doesn't effect anything

[doggy93]

I don't know then. I have the same problem actually.

Do you have a multi core server? if so do you have htop installed? cna you tell me when running the idler which core does the idler max out? is it the same core your srcds is running on sometimes the idler will run on a different core than the srcds server which will have no affect at all. I found the idler runs best on the core of the server you wish eliminate the "bumps" from. Try using taskset to force the idler onto a certain core.

in my experience, the idler does not need to run on the same core as the server. in fact, I have found a single idler to be effective even for all servers running on the root.

have you tried everything that is written in the FAQ / trouble shooting section of the howto? and please make a longer measurement with players on the server (use real players, not bots). the one measurement with players has only a single drop, you cannot derive much information from that...

[christophf]

Hello again,
now my Server FPS are constantly on 1000FPS. I use a Realtime Kernel and some fixes, but when 10 players are on the FPS drops something to 500FPS and in the next second up to 1000FPS how can i solve this problem.
Is there any "trick" in the Kernel options to fix it.
Ilder has no effect, i dont use Chrt.

Thanks for help. Kernel is compilied on 1000hz

[BehaartesEtwas]

give us the link to a fps meter measurement...
why don't you use chrt?

[christophf]

In my Opinion the Chrt is fine for a fast result. But my tests without Chrt, and other kernel configurations produce smooother gameplay.

here are a short measurement. Sometimes the FPS are constantly on 1000FPS u see in the middle of the measurement, but i dont really know how why.
my cyclictest show the kernel delay on 2-3ms

and this is a list of my interrupts, i hope someone can help me

I get better results with a stock kernel, the realtime kernel is bullshit.

[christophf]

What u mean with a "stock" Kernel
u mean vanilla i think ?

In my opinion a vanilla kernel produce some small lags an a unstable connection.

your results are better, which system (os) and with kernel u use when u say that your results are better

[BehaartesEtwas]

I've tried different kernels on many different systems. RT is not always good, but in the great majority it delivers great performance - if correctly used (see my howto).

[christophf]

Thats also my opinion. What is a alternative for a RT.
I used some other like RTAI.

But i dont really know why my kernel is unstable if more than 6 players are on?!?

[christophf]

any idea?

[pengy]

What are the specs of your server?
