I've seen some performance improvements that were lost after build 224 return recently, but it was not until I had a college visiting my desk today and commenting on how sluggish R# was, (he uses 1.5), that I realised I was living a lie!
OK, our solution is by no means small, there are 10 projects, 2400 C# files, 600,000 lines of code. Resharper 1.5 and builds prior to 225 handle it no problem.
The slowness is with the auto-popups when typing in code. I have posted many times before on this issue in the hope it would get fixed. We have 10 developers in our office, however I cannot recommend to anyone they move to the new version until the performance at least matches what they are currently using.
We do not have any large projects in VS 2005, so I'm not sure if this is just a VS 2003 issue. Are there any developers out there who can comment?
So R# developers, please do something or your product will not succeed in the market place. I would suggest generating large projects to test the performance.
