fps performance caused by garbage collection?

[farshizzo]

Is your thread looping as fast as possible and writing data? If the thread is not a high priority then try inserting some time.sleep() statements to give other threads a chance to run.

I have recently dropped the thread in place of a Director() call that save the data to a file. This improves the performance slightly, however I still notice a drop of performance from 60fps to 53fps. Is there a way to set the priority of the Director() call, to a low priority so the thread takes it time to save the file (save the file over a couple seconds as opposed to < 1 second). Adding numerious time.sleeps() does not seem to be a clean way to reduce the priority.

Due to the nature of threading in Python it is not possible to set the priority of a thread. At this point adding sleep statements is probably the easiest solution. Is your file saving thread performing a lot of calculation or is it mostly writing to file? Are you writing data in small or large chunks?

Just for some closure, I have avoided using a thread to save data to the file system and used the director function to handle saving. This improves performance slightly. The problem originates from somewhere else. Someone else might be posting to "Vizard 3.0 Software" regarding this issue.

Thanks for the assistance.
