What is the performance impact of using AddressSanitizer?

What is the performance impact of using AddressSanitizer?

AddressSanitizer can introduce some overhead, typically around 2-3 times slower than normal execution, depending on the application.

Are there specific scenarios where the performance hit is more significant?

Yes, performance can be more affected in memory-intensive applications or those with high allocation/deallocation rates.

Can I mitigate the performance impact while still using AddressSanitizer?

You can optimize your code to reduce memory allocations and use the 'ASAN_OPTIONS' environment variable to tweak settings.

Is there a way to measure the performance overhead introduced by AddressSanitizer?

You can use profiling tools alongside AddressSanitizer to measure execution time and memory usage before and after enabling it.
