Description mawa11 2014-05-30 09:10:04 UTC
Why are Netbeans 8.0 so extremely slow over Remote Desktop (win7)? Screen updates is  really slow and it updates every time I type a letter or open a new file for edit so its really painful. What can I do to make it faster? Bug?

I have tried change the option sun.java2d.noddraw to false with no result. Please help!


netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-Dapple.laf.useScreenMenuBar=true -J-Dsun.java2d.noddraw=false -J-Dsun.java2d.dpiaware=true"

I just confirm what 'mawa11' wrote. I would like to use NetBeans over RDP but it is so slow that it is simply unusable.

It is not caused by a slow network connection - other (non-Java) applications work without trouble.
The CPUs are also fast enough on both the client side and the server side.
I also confirm that toggling the "sun.java2d.noddraw" does not make any noticeable difference.

NetBeans 8.0.2
JDK 8u25 server VM (64-bit)
Windows 7 (64-bit)

I found that switching the NetBeans L&F to Metal helps a lot (i.e. it makes the IDE usable, yet not comfortable).

This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,

I am using NetBeans 8.2 and it still happens.

Apparently direct draw is disabled by default.
Modifying the default options in netbeans.conf from:
Makes it render much faster.
Is there a reason for this to be disabled by default?
