	I sat down today to make some benchmarks of your 8037 file'
server (the one with the twin T300''s) and was appalled by the poor'
throughput.  Using Interlisp-D to COPYFILE a 2.5 mb sysout to or from'
the 8037 took over an hour.  Copying that same sysout with the'
installlisptool took only 1 minute and 14 seconds.  ↑T showed that'
COPYFILE was using \SLOWCOPYBYTES.  Slow indeed!  This is in Fugue6.'
I hope that the next release uses "reasonablecopybytes."'
P.S.  We don''t have an 8037, so this isn''t really a complaint you have'
to worry about.  I''m surprised your 8037 owners stand for it, though.'
