performance: single thread looks OK while multi-thread ( 8 threads) poor .as compared to linux64.
arm machine is with 64-core. it's verified that 8 threads are started. but why is performance much slow？
Did you manage to make any progress with this. If you can let us know the functions in the library that are performing poorly in parallel, especially if you know the platform, then the development team will be able to investigate further.
