Thease are my JDeveloper "performence" settings I use today:
- tools->preferences->extensions
I disabled all the extentions I do not currently use such as ADF, Webcenter ...
I edited my jdev conf file ("C:\java\jdevstudio10133\jdev\bin\jdev.conf") and added/changed the following parameteres:
AddVMOption -Dsun.java2d.noddraw=false
AddVMOption -Dsun.java2d.ddoffscreen=false
#SetJavaVM server
AddVMOption -Xmx1024M
AddVMOption -Xms512M
AddVMOption -Dcompiler.vmargs=-mx1024m
#
# Use this to prevent Windows from paging JDev's memory
# when you minimize it.
# This option should have the same effect as
# the KeepResident plug-in with the advantage
# of being a built-in feature in Sun's JVM 5.
# @see http://java2go.blogspot.com/2007/06/jdeveloper-tips-2-fine-tuning.html
AddVMOption -Dsun.awt.keepWorkingSetOnMinimize=true
