I have noticed that increasing the bench depth produces progressively smaller and slightly faster executables at the cost of longer compile times. Also using bench "time" instead of "depth" seems to produce slightly smaller/faster executables given comparable compile times. I have made a new Makefile that generates smaller and about 1% to 2% faster profile executables at only a little extra compile time. On my mobile 2GHz i7 a full profile build time goes from 3'48" to 4'13" and the exe goes down by 5% from 416,310 bytes to 395,567 bytes. No functional change.
