Whats going on at a JNI call?
I did some benchmarking of JNI calls on x86 and I would be really interested whats going on when a native method is called.
On my C2D I see about 35cycles call-overhead ... I would be really curious what is goind on at a JNI call, which instructions are used and what they are actually doing.
Has anybody had a look at the instructions generated by hotspot?
Thank you in advance, lg Clemens
