- Apparently there's no difference between Debug and Release version, through MonoDevelop, from the speed point of view, in my case: it's a simple ray tracing  console application which involved threading. 
- Also, is the release version of MonoDevelop the same as compiling the code with AOT by command?

AOT doesn't necessarily means faster code. Please attach a test that shows this slowdown.

Oh! Thanks for quick response by the way :)
I will do that. 
thanks anyway.

If it's still much slower with latest mono version, please feel free to reopen the bug. Thank you.
