    My server is running fine and then when i get around 30 users online TPS just drops. At 50 users TPS is at 12-13.

    System has an i5-2500 processor.
    12 Gigs of ram. (This fluctuates between 2 and 10 gigs of free memory using the lagmeter plugin)
    Worldfile is stored on a ramdisk while the server is running, other files on the SSD drive.
    MySQL is running just fine and hardly using any resources.

    Anyone have any tips on what is wrong?

    I have attached 4 timings files for you guys to analyze if you would like to help.

    There is this great plugin called NoLagg. In addition to generally imporving performance, it also has an option to track the resource usage and output them in a graphical from (through a separate utility).

    Added links to the timing, that report show something of the same as nolagg does.
    We are running around 50 plugins just so you know :D

    But does nolagg actually work? We have had cases where it dit not and caused lag in stead of fixing it.

    And our internet is a 100Mbit/100Mbit connection. But maybe its the equipment between that is not up to scratch. Firewall or somtheing. I will look into it, hope you guys will have a look at the timings.

    real time kernel?

    I tried testing the server with 5 players on btw. And the processor is running at 50-60%.
    Would over 6000 mobs be a cause for consern?

    Special kernal with a faster response, original designed for audio and other captureing where delay is critical.
    Often used on CS:S Warservers to increase the tick rate.
