1 solaris 2.5.1 usparc 167mhz?? - SC4.0 cc -fast -Xa -xO5
2
3 For the ultra sparc, SunC 4.0 cc -fast -Xa -xO5, running 'des_opts'
4 gives a speed of 475,000 des/s while 'speed' gives 417,000 des/s.
5 I believe the difference is tied up in optimisation that the compiler
6 is able to perform when the code is 'inlined'. For 'speed', the DES
7 routines are being linked from a library. I'll record the higher
8 speed since if performance is everything, you can always inline
9 'des_enc.c'.

11 [ 16-Jan-06 - I've been playing with the
12 '-xtarget=ultra -xarch=v8plus -Xa -xO5 -Xa'
13 and while it makes the des_opts numbers much slower, it makes the
14 actual 'speed' numbers look better which is a realistic version of
15 using the libraries. ]
