Has anyone noticed the huge increase in CPU utilization by the few recent IB TWS builds? This thing literally kills a single core laptop that used to easily handle running it, so I can use it to cook eggs now. Dual core machines are doing much better, but the process never takes less than 40-50% CPU when the markets are open, and almost never less than 30%.
All this only started happening around 2-3 weeks back, on a pretty much unchanged config.
Which version of TWS are you using?
I noticed problems with 802 but it was taken back again.
801 works fine for me.
Do you run their charts? This may cause the problem.
I use QuoteTracker with IB feed and no IB charts.
