After reading another post by Remi, I guessed it's my responsibility to
reply to my own post here. Yes the problem described above is "normal".
Here is what Remi said:
Yes, with the current core Pentiums are faster than PPro. A 200 MHz
Pentium cracks ~980 kkeys/s when a 200 Mhz PPro cracks ~850 kkeys/s
(test under NT4).
We took the BrydDES core as-is, and it was optimized for the Pentium
(perhaps simply because its author (Svend Olaf Mikkelsen) had access to
only a Pentium and not a Pentium Pro...).
