You will find CPU usage goes way down if you slow
the loop down using sleep(). Even Sleep(10) should significantly
reduce CPU usage. The higher the better of course.

Subject: [DUG] Thread processes
I have a thread that sits in the background
waiting for input from a COM port. the execute method simple has these
two lines:
while not Terminated
do
Application.ProcessMessages;
The problem with this is that the processor usage
is very high, even if the thread is doing nothing but sitting there calling
processmessages.
The main application thread doesn't have this
problem, yet it also has a message handling routine. Is there a way to avoid this problem in threads?
Cheers,
Phil.
