Hi Thorkil
I have been able to use Yhc to run a number of my "serious" toy programs, solving important problems like SuDoku puzzles or finding prime factors of large integers.
Good good, thanks for having the patience to stick around til everything was fixed.
From this, -O2 GHC execution is about 19 seconds, Hugs execution is 5 minutes and 41 seconds (341 seconds) (including compilation, about 3 seconds), and Yhi execution is 5 minutes and 31 seconds (331 seconds).
Overall: For this program (t3), Hugs and Yhc execution times are comparable. Compiled GHC -O2 is 17 times faster.
Yhc should be faster than Hugs, I would guess twice as fast as Hugs normally. If your particular test is spending all its time in libgmp with big integers then that might explain it - otherwise I'd be curious why Yhc doesn't do better. Andrew: Does Yhi get built by default with -O ? Thanks Neil
