When I started using IQFeed, my computer was
nearly out of memeory. I had various problems. After I doubled the amount of
RAM to 4 GB, turned off the real time virus checker, and generally went through
the process list and disabled / removed all unnecessary programs I've had no
problems since.
Another thing I did was to separate the real-time database and historical
database. My RT DB was created with a minimum number of bars to correctly
calculate my indicators. When I'm trading I don't care what happened last week
or last month. I have a second DB that has a much larger number of bars that I
update after market hours that I use for backtesting and code development. This
greatly improves the execution speed during market hours.
Finally, the RT computer is generally left alone. I'm writing this reply on
another PC where I surf the net, read email, run TurboTax etc.

dragging a scroll bar in the symbol list window pane caused it to crash. There
may be other actions that cause the crash, but they seem to involve interacting
with the main AmiBroker window's user interface while the IQFeed plugin for
Amibroker window is up and retrieving data at the same time. Also, sometimes it
seems that retrieving data for more than one symbol simultaneously causes the
crash. Perhaps its a threading issue? I saw some old posts reporting similar
problems, but no resolution.
