Only other issue to bear in mind is that although another CPU and more
RAM/HDD capacity might not make TS4 run better, it may make NT4 run better
and allow more apps to run alongside TS4.
I have 2 450MHz PIIs and 512MB RAM, 2 9GB and 1 18GB HDD and on the whole I
can run anything I like. Some surprising apps make use of the 2nd CPU.

So true. And even if you had an Alpha, you would not see any performance
benefit unless you were doing global weather simulations, synthetic nuclear
explosions, complex protein folding studies, or large-scale,
vector-formatted neural nets. Even if you add a second CPU....even if you
add a RAM disk....even if you defrag your hard drive.
If you have 128MB of RAM, a fast CPU and a modern hard drive, you cannot do
anything else to your hardware to improve the performance of TS4. You can
only get further speed increases by expending mental energy against your
systems to make them faster. I know no one wants to hear this, but it's the
truth.
People overlook a very simple fact when they start drooling over a RAM disk:
NT performs disk caching with all available memory. If you have 512MB in
your system and TS4 and NT together only take up 50MB, you effectively have
a 462MB RAM disk. If you start taking away system memory from NT and your
other applications, they have to swap out their data segments to disk and
any gain you got from the RAM disk is more than lost by paging.

Sigstroker@xxxxxxx:
What good is an Alpha without any software? ;) Your comment is bound to
spark a round of queries from folks wondering how they get TradeStation
running on an Alpha.
The answer folks, is you can't. And only a teeny fraction of all Windows
software is actually available on Alpha. Not aware of a single trading
product.
The reality is that a product like TS shouldn't need such esoteric
hardware...
Regards,
Michael

If you're considering this expense, consider dumping pc architecture and
look
into an Alpha.
