Is it safe to apply these JVM tweaks to IDEA?

Hi,

I've read this article http://www.infoq.com/news/2015/03/eclipse-optimizer which is related on improving the performance of Eclipse by tunning some JVM parameters.

Then I've applied the following changes to the idea64.vmoptions:

- -XX:+UseConcMarkSweepGC

+ -Xverify:none

+ -server

+ -XX:+UseParallelGC

(I've removed -XX:+UseConcMarkSweepGC and added the other three lines at the end)

I've noticed a considerable speed improvement for my IDE (especially since my laptop is a bit older). I've run like this for about a day now and I haven't noticed any side effects.

What I don't know, and here's where the question comes in: Is it safe to apply these JVM settings and run the IDE or not?

I'm on Ubuntu 14.10 x64, with the following java version:

java version "1.8.0_40"

Java(TM) SE Runtime Environment (build 1.8.0_40-b25)

Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode

Thank you for your time and help.

Kind regards,

Florin
