Sorry for the late response.

   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.
