About the multi-thread of the MRCP sever

[不死神鬼]

I find there is 13  alive threads when the MRCP server starts. But there is only 16 cores in my CPU. When I open one client, a new thread will be added to the server. there is a question,  Can I only open three clients at most?  Thanks a lot.

The correlation between the number of cores and the number of threads is not relevant in this context. There is a fixed number of threads launched on the loading of the server. Each thread may process hundreds of concurrent requests.

This assumption is not correct and does not apply to the server. Not sure regarding the architecture of your plugin.

No, you should be able to process hundreds of concurrent requests.

Because I need to do some work such as upsampling , VAD , etc, in plugin, I need to create many extra threads. Will this affect the concurrency performance of MRCP?

You do not have to create a thread per task. A single thread may efficiently handle concurrent requests/tasks.

It depends. There is no short answer to this question.
