Title: I/O priority silent change
Post by: Pelle Positiivi on August 23, 2016, 10:07:10 PM
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. ;D

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.
