Rubymine

I found this only today, you should run Rubymine as 32 bit process. It works much faster and consume half the memory. To set this got to the Applications folder right click on rubymine->get info and check the “open in 32 bit mode” That’s all!

Didn’t find a lot about it on internet so: File->Settings->Editor->colors & fonts->Font first save as current schema than click the … button choose Consolas and set size to 14 looks much better!
