Hello, I have a code that works well with multi-threading class in v9.2.0, but once I upgrade to 9.3.0 the code runs very slow and CPU usage was only 20%. The output of MultithreadInfo::n_threads() is 8 and I could see threads opened, but the speed was about 8x times slower than my previous runs.
Running the example in Step-9 also shows the same issue. Setting MultithreadInfo::set_thread_limit() to 1 or 8 does not change the running time at all. I tried to revert back to v9.2.0, but the multi-threading still did not work...looks like I've messed up something irreversible. Could you help me on this? Thank you!
