Disk caching. Reads are buffered so you can get a track per rev of th=
e disk.
Writes (for DOS anyway) are executed as they come in so you end up wa=
iting
for a disk rev before the next cluster can be written.

If you install 'smartdrv' on the DOS side, things should speed up=
=20
considerably. It also helps to put DOS in highmem with Upper Memory B=
locks
for smartdrv to use as buffer.

In your config.sys
device=3Dc:\dos\highmem.sys
device=3Dc:\dos\emm386.exe

In autoexec.bat
DOS=3Dhigh,umb
lh c:\dos\smartdrv

Have you tried doing the reverse, pulling and pushing from the DOS PC=
?
