- As a note about speed on PCs without going to the level of using
- assembler - in fact without changing a byte of the distribution source
- of MD5, MS C7 will produce the following result:
-
- Ti'ko 486/50, MS C7.0, cl /Oazxb2 /Gr /G2 555,555 Kb/sec
-
- Which compares favourably with the result of the gateway 2000 above.
