I've noticed what you found using CPU monitoring utility program: when
browsing Portfolio or Symbol Universe, the CPU utilization drops
dramatically. It appears the Server stops continuously monitoring
the COM port, perhaps using an interrupt routine instead. Browsing
the Portfolio causes my Server-reported I/O to increase
substantially - from near 0% to nearly 50% or higher.
I run on a Pentium 233 and CPU utilization is not an issue, but high
Server reported I/O, which I presume is disk I/O, slows down the
entire machine and can lead to loss of data. Because of the
excessive I/O when browsing the Portfolio or Symbol Universe, I avoid
doing this doing this browsing during the day. The lack of
monitoring the com port continuously may also lead to a loss of data.
I run a defrag of the hard drive every weekend, which lowers the
Server I/O to nearly 0% during the day session and thus helps the
entire machine run much faster. The first defrag took several hours
for me, where as the weekly defrag takes less than 45 minutes. The
Server must scatter new data throughout the Server file to lead to
such a dramatic difference.

Subject: Reducing Server CPU usage
I've noticed that when I display a dialog box in the Server, such as
"File: Portfolio...", the normally-hoggy server uses MUCH less CPU.
The input queue usually goes up a bit, to 30-40%, but I haven't seen
it go much higher than that. So it still seems to be keeping ahead
of the data stream.
Question: If I'd like to use my system for anything else besides
spinning loops in the Server, is there any harm in just letting it
sit on a dialog box all the time?
