Question

I am having an application which has a UI module and other supporting services. These other services have memory leaks and other thread synchronization issues. Hence in some machines especially quad core, dual core machines the services crash every now and then.

I know the best way to fix this is to clean up the memory leaks and synchonization issues.

But as a work around we set the processor affinity for 2 of those services and observed that the crash did not happen after that.

Now my question is
Will my services take a performance hit as i am limiting them to using only one processor?

Edit 1: Note: These services are multi threaded.

Answer 1

This certainly depends on whether those services rely on threading. If they are single-threaded you won’t notice much difference.

In your case since services are multithreaded they might or might not experience perfomance penalty – this will depend on actual design, specifically on whether they rely on several threads being executed in parallel.
