EQ1 Performance Issues with latest Innerspace

I know most people here probably aren't playing EQ1, but has anyone else see a performance hit with the latest InnerSpace? I've been using InnerSpace/ISBoxer 41 fine for a few weeks, but I got an InnerSpace update today, and my game performance has gone to crap. 6 clients are all sitting at 14-15%+ CPU usage at all times while running via InnerSpace. I fired up WinEQ2 to do testing and all EQ clients are at 3-5%. I can normally run 10+ EQ1s on this box without issues... Via Innerspace 5/6 clients pegs my CPU at 99%.

If you think it's related to the IS update, you're welcome to try previous builds from the archives -- https://www.lavishsoft.com/innerspace/archives

Not sure what it is at this point.

I have two different boxes 1 is a windows 8 box, and the other is windows 7.
I wasn't getting the same issues on the windows 7 box as I was the windows 8(using latest and greatest Innerspace Build). I've uninstalled Innerspace/IsBoxer on the windows 8 box multiple times, and still getting issues. Windows 7 box has been running great, until today. After the EQ patch today my Windows 7 box is running like the Windows 8 box, each instance is taking a steady 10-15% CPU and loads 700-1gb of memory.

I've been using innerspace specifically for ISBoxer group profiles / key maps / repeater... I am able to use WinEQ2.15 to resolve the performance issues, but I lose all the benefits of Innerspace. It's playable if I use MQ2, but I was trying to stay legit this time around :) Running WinEQ my instances take about 500mb of ram, and each instance sits around 2.5% CPU usage.
