Can we change the thread number while running the application?

[Mr-Phoebe]

When I run linear locally, I find there is a config.proto where I get some parameters, such as max_concurrency and num_threads .

But when I change the num_threads , the efficiency wasn't improved. After I read the src, I wonder whether the num_threads can change through the config, and how can I get the thread number of the application.
