What are the performance considerations when using mutexes?
When using mutexes, consider factors like contention, lock granularity, and the overhead of acquiring and releasing locks.
How does contention affect performance?
Contention occurs when multiple threads try to acquire the same mutex. High contention can lead to significant delays.
What is lock granularity?
Lock granularity refers to the size of the resource being locked. Finer granularity can reduce contention but may increase complexity.
Are there alternatives to mutexes?
Yes, alternatives include read-write locks, spinlocks, and lock-free data structures, each with its own trade-offs.
How can I measure the performance impact of mutexes?
You can use profiling tools to measure the time spent in lock acquisition and the overall throughput of your application.
