Is anyone else having recurring lag issues since the update from 6/25/2011? I am having lag issues that TOS keeps insisting is on my end. I have ridiculously powerful hardware, tons of memory and a solid internet pipe. What I am seeing is smooth performance interrupted by peculiar lag spikes that do not pause the quote feed, but that do pause the interaction to the order server. This manifests itself with an inability to adjust stop orders on the chart, late fills, etc. It's a nightmare when you're trading futures. During the lag spike, in order to test my general connectivity, I turn to other internet-based software and run some speed tests. I see no problems with any other internet software during these spikes. They last for about 20secs to as long as a full minute and are frequent -- about once every few minutes. I have contacted tech support several times now they seem completely unable to help. "Get more memory" "Clear out your thinkorswim folder" etc. etc. I have tried everything they suggested as well as reinstalling the software. I have no viruses or spyware on the machine. The box is CLEAN. I am looking for some other people to confirm this issue. I am at my wits end with this. Thanks for any feedback.
