"Everything is working great with the API. I love it." - Comment from Calvin
"With HUGE volume on AAPL and RIMM for 2 days, everyone in a trading room was whining about freezes, crashes and lag with *******, RealTick, TS and Cyber. InvestorRT with IQFeed was rock solid. I mean SOLID!" - Comment from Public IRC Chat
"I've never had DTN go out on me since switching. ******* would go down a couple times every month when I was using them." - Comment from Bryce in AL.
"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

Not sure if you are seeing this elsewhere but our clients are typically opening hundreds of streams and a couple were having terrible performance during the New York open and close.

One of the items we discovered when working with these clients was that their Documents folder was being synched to One Drive. The issue is that the IQConnect log file (which can be over 7 GB for a whole day session) is in {Documents}\DTN\IQFeed

Once we changed the registry setting for the users, there was a marked improvement in performance.

I would suggest that you find a better place for this file given that all new installs of Windows make it so that you have to Opt-out of documents being backed up to One Drive. AppData or ProgramData would be a better place.

This behavior hasn't changed recently that I know of. I'll speak to the development team about it and post findings here.
