Hi Alex, Your results are great!! Thank you so much. I want to confirm something. Inter-AS Call(10) 1008 What is meaning of "10" ? Inter-AS Call 980 Inter-AS Call (Low to High) 1050 Inter-AS Call (High to Low) 1463 Here, "Low and High" means the priority of process, right? So without that, it means those two process have same priority. Is this true? Thank you. Yuxin On Sat, Oct 18, 2014 at 10:56 PM, Alexander Kroh < Alexander.Kroh@nicta.com.au> wrote:

Hi All,
I find there have slow and fast path for IPC. I want to know the performance difference between those two. More accurate, on x86, how many cycles for slow path round-trip ipc between two address space?(on single core) And how many for fast path?
Thank you very much.
Yuxin
