I've been trying IDEA 13.1 with the Java EE Application of my company. My goal is to convince my boss so we can make the switch from the old MyEclipse!
I configured everything I needed and got it running as I expected. I even configured the hot swap just like this article describes.
However, hot swapping is so slow. It's taking me about 10s to make and hot swap.
I don't know if this is because the application is large (legacy codebase of roughly 10.000 files) or if it's because we use a old JBoss 4.2.3.
MyEclipse, in the other hand, does such hot swap almost automatically all the times.
My current configuration is Windows 7 and IDEA 13.1.4 (build 135.1230).
