Well if you recommend and expensive hardware fix, and that doesn't fix it
it could be your last day.

Before you go stumbling about blindly, give us some more information as to
hardware (all of it) software, etc.    I have seem some software programs
that no amount of horsepower would solve, because people didn't understand
what was going on.

An example from a local bank. They had a process running that was doing
massive amounts of calculations.   Took 24 hours to run, and that was after
they had gone to a 25Mhz '386 with 16 megs ram.   Friend of mine went in,
looked at the code, did about one hours worth of work, and it now ran in 4
hours.

Give us all the symptoms and then re-ask your question.
