Question

I’m trying to understand whether a process would interfere another process running on the same piece of hardware system. This could happen in a wild range of products. ie. vmware or as simple as running multiple .net applications.

If I have repetitive lock happening of a particular process say, interlock, or lock keywords in C# terms, will it affect the performance other processes due to its intensive usage of lock? The setting is a heavy loaded www system, and I am experience some situational delay, I would like to determine whether the delay was caused by a dense while loop of locks that was completely isolated by a different windows kernel thread.

If there is no isolation, will application domain in .net help me in this case?

Thanks for your answer

No it won’t. A lock in C#, and .Net overall, is local to a process. It can’t directly affect other processes on the machine.

A lock statement operates on a particular instance of an object. In order for a lock to effect multiple processes they would all have to lock on the same instance of an object. This is not possible since objects are local to a process.
