Hello everyone,
I know this might not be right thread but I'm really desperate with everything around Java because it usually does not work for me

And I have recently installed fedora 23 and found that all java applications start extremely slow, I have installed both openJDK or Oracle Java
* 1 /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.91-5.b14.fc23.x86_64/jre/bin/java
+ 2 /usr/java/jdk1.8.0_91/jre/bin/java



does anybody know how to debug start of java applications? Because I takes like two minutes to start pycharm on my computer which has quite decent params:
CPU: intel i5
RAM: 8GB
storage: SSD (OS), HDD(data)
OS: Linux oglop-pc 4.4.9-300.fc23.x86_64 #1 SMP Wed May 4 23:56:27 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux


./pycharm.sh
OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=350m; support was removed in 8.0
May 16, 2016 12:54:11 PM org.lobobrowser.main.ExtensionManager createExtensions

It took 2 minutes to start, I'm experiencing similar behavior with all Java applications, like FRD or Mineshafter launcher.
I would be glad if anyone could help me.
Thanks
