I've been using pkunzip alot under ISC/VPix lately.  While the
program seems to work at the same speed as native DOS, writing
to our Micropolis 320meg scsi is noticably slower than if I access
the DOS partition via native DOS.  This was true even if I was
the only login.  In fact, I installed some commercial software
(about 10megs worth) on the dos partition by booting DOS from
floppy because disk writing seemed faster to me than doing the
same from VPix.

Any comments?  For your reference, the computer is an Intel 
model 302, 25mhz, 8meg.

BTW- the above is not true when VPix is writing to the unix
partitions.
