Follow up on GC locking Windows threads
posted Monday, 26 September 2005
In an earlier blog entry I explained how a friend of mine was experiencing Windows studdering in the late afternoons. I had heard rumors that the JDK 1.5 could block high priority threads running in Windows but I could never confirm that this was happening.
Now, thanks to some exploration work done at Java Gaming, it has been reported to Sun that threads running in the JVM can *indeed* block high priority Windows threads. This is because there are more then a dozen threads running at priority 15. This helps...
-XX:JavaPriority10_To_OSPriority=10 -XX:JavaPriority9_To_OSPriority=9.
