  I have found in the past that the assembler we used did not align text 
properly. When the compilers skip the assembler and generate direct object
code they do the alignment properly, alignment wins. Check your final code image
to see if entry points are really aligned. I found that random variations in
the alignment, caused by code template changes I was trying, were on the order 
of +/-3% and masked any improvement I was looking for. Things became very 
repeatable when alignment became stable.
