So now I am down to the timers... I am using TFPTimer timers in the scheduler to handle various things, some of them are just one-shots to delay an action for some predetarmined time. These are only executing as one-shots. But the schedule timer restarts itself with an interval of 60 s. Another timer is used to handle a message queue between parts of the system. It runs at a shorter time, like a second or so. Restarts itself too. But it runs only if scheduling is active. I have no idea how TFpTimers work internally, maybe these cause extra CPU cycles while waiting for the time they should fire? I could switch off the scheduling timer, but it made no difference. The other timers running for other purposes I canot disable. An these fire more often. Right now the server is running at 10% when doing nothing, not even checking schedules... After I did a service restart it drops to about 5% -- Bo Berglund Developer in Sweden _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
