I have been an avid user of IntelliJ IDEA since I first saw it about 2 years ago. I have been tracking the changes that it has been going through with a lot of interest. I currently use IDEA 3.0.5 for doing my work. A week ago, I downloaded the latest EAP build. I was looking forward to seeing all the new features that have been put into the product since the 3.0 series.
However, I was pretty disappointed. As a person that works on really large projects, the usability of the EAP release was not good. I am continuously adding and removing paths from the project settings. We upgrade library files, checkout branches, etc during a normal workday. So, the first thing that I noticed was the whole "Optimizing Performance" dialog fiasco. I found the older threads discussing the topic but was unable to understand what had changed since the 3.0 series that required this process. The 3.0.5 release, for example, performed quite well for all refactorings. I never noticed a performance problem on my 1 GHz PIII laptop. The optimizing performance process, on the other hand, is noticeably slow and unbearable. It takes forever on my box. It is bad enough that I wouldn't want to upgrade to a new release even if it was free.
I am hoping that someone on this forum would take into account this feedback and would let this unhappy user breathe a little easier about the future of his favorite IDE.
