Hi
I repeated tests. I wrote a set of simple functions. It is a synthetical
test, but I think it can identify potential problems well.
I calculated the average of 3 cycles and I checked the performance of each
function. I didn't find any problem. The total execution time is well too.
Patched code is about 11% faster than master (14sec x 15.8sec). So there is
new important functionality with nice performance benefits.
make check-world passed
Regards
Pavel
