I can't tell yet because there's either a missing e-mail on list from you, 
or it's just because all your e-mails to the list are mashed together 
without any CR's and it's hard for me to parse them out, but it looks like 
you're sending me code optimizations again.

As previously discussed, I'm not applying any pure code optimizations until 
after FreeDOS 1.0 release.  Some of the ancient code in there is simply too 
fragile to mess around with unless a bug is involved, and there are better 
uses of the limited development, testing, debugging, and user resources in 
tracking and eliminating compatibility issues.  But, to give credit where 
due, you're only a bit early now.  Post-1.0 is a good time to discuss 
possible optimizations with whomever is the maintainer at that time.

I did see a specific discussion of REP MOVSD.  We also talked about that on 
list here too, along with a couple others.  To be properly optimized, the 
code needs to track the CPU and make optimizations based on the chip.  REP 
MOVSD is the best generic and simple optimization for quick development for 
a broad spectrum of computer types.
