question about lo_unix_scall

Subject: question about lo_unix_scall

Hi

I'm trying to investigate performance regression

we noticed that our new release is much slower than previous one

when I run both with Shark (on the same computer)

I can see that new release has much more (10% against 0%)

mach calls like lo_unix_scall, unix_syscall,

ml_set_interrupts_enabled, sigprocmask

I didn't see those calls in our previous release when I run it in exactly the same environment

what does that call mean?

thank you very much in advance

Dmitry Markman
