Garbage collector
If the garbage collector is working overtime, it may consume a lot of CPU cycles. Check the counters shown in Chapter 3, Memory to see if this is the case, especially % Time in GC. To see how to check a counter in perfmon, refer to the Pinpointing bottlenecks section, the Thread usage subsection in chapter 2.
