It depends a little on what kind of "speed" you are looking at.  In
terms of raw computational speed, which would matter the most if you
are doing lengthy cpu-intensive calculations, the OS/2 version overall
is faster than the windows version (see

If your calculations are short computationally, then the speed of the user
interface is what will matter to you.  In this case it is a mixed bag.  The
OS/2 version comes with two user interfaces - the native PM interface and the
windows-based notebook interface.  The PM interface is basically text-based 
sequential input with graphical output capability and is very fast but it is 
somewhat limited and is not document-oriented.  The windows notebook 
front end runs in a win-os2 session and communicates with the kernel via 
tcp/ip.  The windows interface is fairly slow (apparently
due to the tcp/ip and mathlink overhead) but is document-oriented and
contains pretty good on-line help.  I use both interfaces - each one is
a better match to different tasks.

If you are going to use the windows front end with the OS/2 kernel, I
would recommend at least 16Meg of RAM and 32Meg of swap space for decent
performance.  I have 12Mb and the system tends to swap heavily after 
a certain amount of usage.

The help system for the windows (win-os2) front end is pretty good and
contains help for kernel commands as well as front end commands.  The
help for the PM interface is good as far as help for the interface is
concerned, but contains no on-line help for the kernel (of course the
built-in Mathematica "?" function is always available though).
