Is the method trace safe for multithreading?
The method Trace () is multithreading safe, non blocking and can be called from any thread. On my PC, it takes about 2 microseconds to execute, which should be fast enough.
What’s the best way to test for multithreading?
In addition to the other good answers you already got: Always test on a machine with at least as many processors / processor cores as the customer uses, or as there are active threads in your program. Otherwise some multithreading bugs may be hard to impossible to reproduce.
How to detect and debug multi-threading issues in Java?
Acquire locks in a set order and release them in the opposite order. Use pre-built abstractions whenever possible (Like the stuff in java.util.concurrent) Also, some analysis tools can detect some potential issues. For example, FindBugs can find some threading issues in Java programs.
Is it possible to replicate a multi-threading problem?
Threading/concurrency problems are notoriously difficult to replicate – which is one of the reasons why you should design to avoid or at least minimize the probabilities. This is the reason immutable objects are so valuable.
When does lock contention take place in multithreading?
Use I/O completion ports as solution. Lock contention takes place when a thread tries to acquire the lock to an object which is already acquired by other thread*. Until the object is released, the thread is blocked (in other words, it is in the Waiting state).
How to check thread contention in Stack Overflow?
This counter displays the total number of times threads in the CLR have attempted to acquire a managed lock unsuccessfully. Managed locks can be acquired in many ways; by the “lock” statement in C# or by calling System.Monitor.Enter or by using MethodImplOptions.Synchronized custom attribute.
What happens if Thread C does not need a lock?
If thread C doesn’t need that lock, then future contention between threads A and B can be avoided for awhile. (Of course, this assumes there are other threads that could run.
