The oprofile as well as --profile=default:stat shows that the difference
lies in GC, precisely in GC_mark_from, other functions are generally the
same. And the difference in GC_mark_from is like this 10%.
I can try checking x86 later, but it will require some setup. Anyway the
difference should be also seen in mcs bootstrap.

"large file upload"? I don't get it.
