Here are some quick benchmarks i collected for dcypher.net CSC contest.
To get keys/sec divide Kbps by 64.
p2-266       45000Kbsp       703kkeys
p2-400       70000Kbsp      1092kkeys
k6-3/400   60500Kbsp        945kkeys
k7 600     120000Kbsp        1906kkeys
k6-200       14000Kbsp          218kkey(Integer code is faster than single issue mmx)

You will find that on dual issue MMX cpus, CSC is about the same speed as d.net RC5 for P6 family and about 2x faster than d.net CSC.
K6-2 users will be significanly faster than d.net rc5.
K6 users will still suffer =)

To sum it up, Dcypher.net has faster clients for dual issue mmx boxes.
Unfortunatly I dont have any non mmx machines around to bench..
