I don't know what the OpenSSL people did to the x86 ASM code, but SSLeay
 (the precursor to OpenSSL, over 3 years old)  did/does 330 512bit and 
55 1024 bit
RSAs a second on a 333mhz celeron (linux and/or win32).  You should be 
seeing
numbers like 600 and 100. The company I work for has 70 1024's per second
on the celeron 333.  It used to build this way (and with this 
performance) for
most x86 boxes.....

PS    The SSLeay version I tested was '0.9.1a 06-Jul-1998', which is 
what is in
    \bin on my laptop.
