Resharper 6.1.1 Performance Problem!!

I have been a fan for Resharper and would like to deploy one for each of my new development team. But .... lately I have experienced several severe performance problems with 6.1.1 version (C#). I hope Resharper can tackle these problems and give a fix asap.

1. Memory usage: this is a known issue for a long time but just to highlight some data. My Visual Studio 2010 takes up 800MB working set when our development project is loaded. While without a resharper installation, my college's application only takes less than 270MB. Both of us are using Dell Workstation T3500 and Windows 7 Professional SP1 (64-bit). I have 12GB memory while my college only has 4GB.

2. Slow startup. I don't have a comparison here but it takes my VS2010 more than 1 min to (warm) startup and finish loading the solution, which contains only 16 small projects.

3. From time to time I am experiencing lags while typing code. Well, this is probably a long-living problem but I didn't feel it so frequent with 6.0 version.

4. Today my VS2010 HANGS :O:O:O for mroe than 7 mins just because I was trying to delete some obsolete references from one of the projects. The CPU usage was 50% all the time for my dual core and I had to kill the process after long waiting!! This was a never experience with prior versions. I just can't imagine what task requires such huge computations!
