Using 2.5 beta vs 2.4 on DOS or Windows, I find 2.4 to be 
significantly faster on this, by about the same ratio as you
show above, *but* using my latest build of 2.5, 
I find 2.5 to be a bit faster than 2.4. I don't know why, 
but modern CPU's are very complex, and small differences 
in the machine code stream can sometimes make a big difference in time. 
I don't recall tweaking anything to do with types or calls in 2.5, 
certainly not since 2.5 beta came out.
