The [visualizer site](https://jmh.morethan.io) is added to the PR description. The JSON file can be dropped there. > Is the multithreading mode really useful? NMT records stack traces for threads in a different way as of other threads. It uses a link list for the former and a static hash table for the latter. I tried to make a more realistic use case of NMT. > THREADS=2, WITH_THREADS=0 > THREADS=4, WITH_THREADS=0 > THREADS=8, WITH_THREADS=0 The last two rows of the above list are skipped now.

For `NMT_Off` for example, there are 2 (no of threads= 0,4) measures per method. Consider also, we will have more methods for virtual memory alloc/dealloc tests. ------------- PR Comment: https://git.openjdk.org/jdk/pull/15563#issuecomment-1709605094 PR Comment: https://git.openjdk.org/jdk/pull/15563#issuecomment-1709607490 PR Comment: https://git.openjdk.org/jdk/pull/15563#issuecomment-1709610021 PR Comment: https://git.openjdk.org/jdk/pull/15563#issuecomment-1709815642 PR Comment: https://git.openjdk.org/jdk/pull/15563#issuecomment-1719651603
