I have a pretty sizable console app written with Delphi 15 years ago but ported to Linux using FreePascal (3.2.0) with Lazarus (2.0.12) as IDE. It runs as a systemd service on a Raspberry Pi3.
Basically it is a scheduler, which checks every minute if there is a task to run, otherwise it waits for the next minute to pass. Meanwhile in another thread there is a TCP/IP socket server active for communicating with the app over the network. So it is listening for incoming connections. This is working seemingly OK, but today when I checked the RPi I found using top that it was running 11% CPU, which is strange because it has nothing to do at the moment. I have tried to be as conservative as possible regarding wait loops etc so in such loops I always have a sleep() call, which in my Windows experience used to stop excessive CPU usage. So I was surprised to find the high CPU usage and now I am at a loss on how to find *where* this is happening... Any ideas on how to proceed? Is there some Lazarus way to find this? (But I cannot really run the application in service mode from within Lazarus...) -- Bo Berglund Developer in Sweden _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
