I/O priority silent change

[Pelle Positiivi]

Hey,

An application got I/O priority lowered from normal to low during runtime and I couldn't find that event from logs, what can cause this? I searched with the file name, found other events but nothing about lowering I/O priority  .

Then it is changed by other processes, and Process Lasso can't know who did that.

Usually this happens because the program was launched by the Task Scheduler and inherits it's low I/O priority. Alternatively, the program (or something else) changed the priority, but probably it is the first scenario . So, no change may of happened, it may have started that way - but these changes are indeed not logged in any event, as one can only log so much.
