| 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. ] | ||
