I recently upgraded to the 2016.2 release and was finding the UI very laggy, typing in an editor even had a noticeable delay, sort of like when you're typing on a laggy SSH connection. Scrolling was jerky and everything was pretty bleh.
Performance was similar to issues I had late last year which turned out to be related to Java 8 not really playing nice with Macs with retina displays, that issue was resolved by installing the Mac release of Java 6. However I noticed that in more recent versions of datagrip that problem seemed to be resolved even when using the bundled OpenJDK 8. So I tried fiddling with the JDKs again, trying older versions and what not, however the issue remained.
I eventually just downgraded to 2016.1 and my problems went away. I have noticed the 2016.1 is actually using the exact same openjdk release 1.8.0_76 as 2016.2 was using... so it seems likely that these performance issues are specific to that release of Datagrip.
Anyone else seeing this?
Datagrip peeps: what can I do to help diagnose the issue so you can fix? I was really looking forward to using the improved CSV importing of 2016.2 since that's something I do a lot!
