Description mvogt1 2015-11-13 15:05:41 UTC

this bug/feature is around since netbeans 6.5 and is still valid
in 8.0.2 and 8.1.

I have started netbeans from an indirect session:

X :1 -query <host>

or you can login into a remote host with X11/ssh forwading, to
reproduce it. 

The Menus on the remote X11 Menubar are incredible slow!

There was a time when this was true for eclipse as well, but
eclipse works nice on remote X11 (ssh or query) now since a few

(This shows me that there could be a solution.)

The workaround mentioned here:

did not work for me.

Please provide additional information:
1) attach messages.log file
2)  use 'Profile Me Now' <> and attach the snapshot - this way we will know, what is going on when menus are drawn.

- attached performance file

But I don't know how to get the messages.log file.

My profiling was.

- start profiling
- click on "FILE"
- wait until menu appears
- press cursor right
- wait until menu appears
- presse cursor right
- etc...

netbeans uses AWT, the dropdown menus in the IDE are slow too.
The switch of the TAB view is fast.

- same with OpenJDK 1.7.x
- oracle JDK 1.8.x

The messages.log file is stored in your $HOME/.netbeans/8.0.2/var/log directory.
