JDeveloper Performance Tuning

There are couple of things to be taken care.

1. JVM Parameters

a. Open your Oracle Home directory that we set up when installing JDeveloper, and
navigate to %MIDDLEWARE_HOME% | Oracle_Home | jdeveloper. There are two files
that you want to change: the first file is ide.conf located under ide\bin\ide.conf.
b. Open the file using your favorite text editor and locate the following lines:
AddVMOption –Xms
AddVMOption -Xmx

2.  JVM Extra Optimization Parameters

a. Open the jdev\bin\jdev.conf path under the jdeveloper directory. Add the following entries at the end of the file:

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

b. # if on a 64-bit system, but using less than 32 GB RAM, this
reduces object pointer memory size
AddVMOption -XX:+UseCompressedOops
c. # use an aggressive garbage collector (constant small collections)
AddVMOption -XX:+AggressiveOpts
d. # for multi-core machines, use multiple threads to create objects
and reduce pause times
AddVMOption -XX:+UseConcMarkSweepGC
AddVMOption -XX:+UseGCOverheadLimit
