Increase the performance of JDeveloper 11g

The following settings will increase the performance of your JDeveloper 11g.

Go to your JDeveloper root directory (JDEVELOPER_HOME/jdeveloper)
Open the file ide/bin/ide.conf, and change memory settings to something larger, like so:

AddVMOption -Xmx1024M
AddVMOption -Xms1024M

Open the file jdev/bin/jdev.conf, and increase the value of MaxPermSize:

AddVMOption -XX:MaxPermSize=512M

Add the following settings at the bottom.

# optimize the JVM for strings / text editing
AddVMOption -XX:+UseStringCache
AddVMOption -XX:+OptimizeStringConcat
AddVMOption -XX:+UseCompressedStrings

# if on a 64-bit JVM, but using less than 32 GB RAM, this reduces object pointer memory size
AddVMOption -XX:+UseCompressedOops

# use an aggressive garbage collector (constant small collections)
AddVMOption -XX:+AggressiveOpts

# for multi-core machines, use multiple threads to create objects and reduce pause times
AddVMOption -XX:+UseConcMarkSweepGC

# to activate memory monitor
AddVMOption -DMainWindow.MemoryMonitorOn=true

Open the file jdev/bin/jdev.boot, and remove the # before VFS_ENABLE property.

# This will enable a "virtual" file system feature within JDeveloper.
# This can help performance for projects with a lot of files,
# particularly under source control.  For non-Windows platforms however,
# any file changes made outside of JDeveloper, or by deployment for
# example, may not be picked by the "virtual" file system feature.  Do
# not enable this for example, on a Linux OS if you use an external editor.

Go to your user root directory.
On a Linux OS, open the file .jdeveloper/system11.1.1.7.xx.xx.xx/DefaultDomain/bin/
On Windows OS, open the file AppData\Roaming\JDeveloper\system11.1.1.7.xx.xx.xx\DefaultDomain\bin\setDomainEnv.cmd.

Change memory settings to something larger, like so:

set XMX_SUN_64BIT=1024
set XMX_SUN_32BIT=1024

You can use the Java VisualVM to monitor JDeveloper.
Go to your Java root directory, and execute the file bin/jvisualvm.exe.


You will find some useful -XX options here:
