That is a tough question to answer in general. You don't mention if you are
using MetaStock Professional or EOD. I ask because obviously the demands on
your computer hardware are much higher for Professional.
In a general sense, running more programs simultaneously places more demands
on your hardware. The more applications that are running, the more time
your system spends context switching between applications and trying to
manage the competition for resources (CPU cycles, physical memory vs virtual
memory, etc). The more time your computer spends just trying to manage
simultaneous applications the less time is available to actually let those
applications perform their duties.
Many other factors can also be involved such as how much memory and free
disk space your system has, how fragmented your hard drive may be, and of
course the speed of the CPU. Also, MetaStock itself can place high demands
on memory (both Professional and EOD versions) if you choose to load large
amounts on data into charts. Add a few indicators to those charts and your
system may spend a lot of time trying to manage virtual memory, making your
whole system seem slow.
Once again, in a general sense, when using MetaStock, run only those
applications that you absolutely need. Also, simultaneously load only as
many charts as you need and keep the amount of data in each chart to a
minimum. Do not overload the charts with more indicators or experts than
you absolutely need. As an example, if you want to look at 60,000 data
points in a chart, your system will run more smoothly if you open one chart
at a time. Otherwise, 60,000 data points in 5 open charts will place much
higher demands on your system.
Regardless of the available resources on a computer, it is not all that
difficult to overwhelm a system (especially with real-time updates on a
heavy trading day) if you don't practice some basic resource management of
your own.

Subject: Hey, PD MAN
Ken,
You've heard a lot of our frustrations. Maybe, it would be helpful to give
us some advice on how we can get overall optimal performance out of this
quirky program. ie. Should we avoid simultaneous running of other programs.
Which will give us better performance IE or Netscape? Are there any
parameters that we can set to really bring our programs alive? Thanks
J.
