Re: Mach lack for frequent operations

[Matheus Morais]

I think this is a implementation problem, there is no way to fix it. Maybe this can be fixed rebuilding all Mach infrastructure. Can anyone confirm that?

 

Thanks

  Can anyone explain why that overhead happen in Mach?

The large overhead is mostly related to how the Hurd uses Mach.
Running a single-user server system gets you quite decent performance,
but we have a multi-sever design, where the number of context
switches, and IPC overhead is becomes far larger.
