interval when GC is runWhat is the interval when garbage collection is run and is there a way to
monitor it through Perfmon? Hello Roger,
There is no time interval, GC runs in 3 cases 1) Allocation exceeds the Gen0 threshold; 2) System.GC.Collect is called; 3) System is in low memory situation; R> What is the interval when garbage collection is run and is there a R> way to monitor it through Perfmon?

The threshold of GC is not cleary fixed, it depends on CPU cache. AFAIK there is no perfcounter to monitor this But, could u explain why do u need to monitor this?

(c) Friedrich Nietzsche Well, I have an asp.net 2.0 app, and I have a a few singleton objects
declared. And for some reason, I can navigate around for awhile and then for no reason and never in the same place and never the same time, during development I can thrown out. If I look at the detail info, it is on one of my objects. Cursious to determine is GC is collecting it or not.

Try to play with these counters .net CLR Memory/# Bytes in all Heaps .net CLR Memory/% Time in GC .net CLR Memory/Large Object Heap size .net CLR Loading/Bytes in Loader Heap .net CLR Loading/Current Assemblies R> Well, I have an asp.net 2.0 app, and I have a a few singleton objects R> declared.

All you need to know about GC -- just check-out Jeffrey Richter's explanations: http://msdn.microsoft.com/msdnmag/issues/1100/GCI/default.aspx http://msdn.microsoft.com/msdnmag/issues/1200/GCI2/default.aspx Also you can find some information about GC monitoring.
