Scheduler


So what's the blurb about the scheduler. Well, basically the Operating System has different parts which run in parallel and the way the processing power is distributed between them changes the way the server performs under high load. If other processes run on the same computer it will therefor influence how much cpu time hssTVS gets compared to them. A setting of 2 for the scheduler will shutdown all other services with a lesser priority in case the server is under maximum load, so handle that carefully. However, if you use the computer mainly as web-server you can get a bit better response times with a high setting here, but normally just changing the nice value to -20 should be enough to guaranty good performance and a fast initial response.
  • sched
    sets the scheduler pattern. 2 is FIFO, 1 is RR, 0 is OTHER, default 0.
  • nice
    In case main_sched is 0, this value represents the nice value (-20 to 19 with -20 highest priority) with a default of 0. For the scheduler setting of 1 or 2 this is equal to the priority (1-99, with 99 max) of the program, default is 1.
