Wow! Maybe I should not upgrade to 41 since my 10/30 does 161290 !
What C-compiler are you using? Mine is gcc 2.1 (gcc -O). I  have an old
version of sun C so I don't use it very much...

(maybe you used the c-compiler that comes with the system... that doesn't
generate good code.. you should buy the compiler separately)

After running byte benchmarks on ss10/30 and hp 720 I don't somehow trust
these results. SS10/30 was able to keep up over 2meg on file copy where as
720 did only 700 kb! The file size 250 blocks makes me a bit suspicious..

How much memory did 735 and 10/41 have? What kind of disks?
(720 had 64 meg, ss10/30 32 meg, disk for ss10/30 was maxtor scsi-2..
I don't remember the type numbers now.., I don't know about disk type
used with 720 in byte benchmark because the result was included with the
source). I actually run the test by myself on 720 but the result was
even worse 300 kb! 

Where did you manage to get 10/41 anyway????
