background threads pause on app focus lost

not_a_commie

I have a background thread running in my application. When my
application loses focus there is a 200 to 500ms delay in the execution
of my background thread. Is this normal? Setting the process and
thread priorities to "above normal" makes it a little better but there
is still a long delay. Any other way around this issue? I'm running on
winXP with .Net 3.5 sp1.

It really depends on what else is going on. What are the background
threads doing? Does your application do anything else when it loses
focus? How do you make it lose focus? What application gets the
foreground, and what is it doing?

I'd say that a 200-500ms delay wouldn't be typical just as a result of an
application losing focus. But there certainly are reasons why that
_might_ happen to an application.
