It is a common observation that MMA 2.2 runs much slower on the Windows95
platform. One of the fixes that Wolfram offers is very effective in
bringing MMA close to its Win 3.1 speed. The good fix is adding
Install["addtwo"]
to the init.m file in the WNMATH22 directory. The "<<procup" fix is
worthless and makes things worse by causing everyting else to slowdown. How
this works is well explained on www.wolfram.com.
I present the timing findings on my machine, ****MY MACHINE**** which is a
Micron P120/24 MB running WIN95 and MMA 2.2.3 with the fix in place. The
tables were furnished by

The timings without the fix in place are not included but are 2 to 6 times
slower.
You can paste the notebook given below into your machine and see how it
stacks up.
