tokio's example default features is enable "rt-multi-thread" We know that when this is enabled, task stealing occurs inside Tokio and this feature severely affects performance (at least twice as slow).

I think a comparison should be made with Actix-Web(It is based on Tokio), which uses a separate runtime for each thread.
Another option is that may and Tokio both limit the number of threads and ensure that Tokio uses a single-threaded runtime

It's very old comparation. you can just ignore that. the TFBshould be a good place to check. May is using a scheduler which is something like tokio's "rt-multi-thread"

Can may provide type to use a separate runtime for each thread(have no task stealing)? just like actix. In some scenarios, cross-thread stealing is not necessary.

The design was only considering the work stealing pattern. But implement a non work stealing scheduler is possible and may result a huge change of the project. I have no plan to do that.
