I installed juno RC1, RC3... and was counting the seconds to installing the release version on the 28th! But now, after installing and using it in full power for a few days, I am a bit disappointed with the slow response: I have a few java sources open and a few hibernate mappins as well, and eclipse seems to freeze and take an enormous amount of time to switch between tabs... I have a lenovo thinkCentre with 4GB so I don't think the problem is the hardware... plus, this never used to be so slow with eclipse Indigo... Anyone else having the same problem?
