IDEA is very very slow

Hi guys, good evening.

I have a AMD FX-8350, 32 GB RAM, Fedora Core 20 development machine for work. It has a R9 290 video card.

I don't understand why the performance in IDEA is so slow. I have tried giving it 8, 12 gigabytes of RAM via the vm settings file, it only improves marginally.

I have disabled every single plugin except Scala, html and javascript which is what I'm working on.

It is still so painfully slow. I've turned off syntax highlighting and even used "mark as plaintext" (!!!!) and it still is slow!

Something is definitely wrong here.

I've decided to post only after I tried all the tricks found on Google for "intellij idea is slow", so I think I've covered the basics.....nothing worked.

IntelliJ IDEA 2016.2.4

Build #IU-162.2032.8, built on September 9, 2016

JRE: 1.8.0_112-release-b343 amd64

JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o

I'm using the Oracle VM, does this cause troubles with OpenJDK?

Linux kernel 3.19.8-100.fc20.x86_64 #1 SMP

x86_64 x86_64 x86_64 GNU/Linux

top - 22:32:41 up 1 day, 5:46, 11 users, load average: 2.75, 2.86, 2.69

Tasks: 323 total, 1 running, 322 sleeping, 0 stopped, 0 zombie

%Cpu(s): 5.4 us, 9.7 sy, 0.1 ni, 83.4 id, 0.0 wa, 0.0 hi, 1.3 si, 0.0 st

CPU is cool, system has less than 2 concurrent tasks avg for 8 cores....it's definitely not a hardware issue.

Any tips appreciated. Thank you.
