JDev 12c Performance Improvement tips

Hi All,

When working with ADF 12c project with JDev 12c(12.1.3.0.0) I faced issues related to J Developer slowness.

So, from the online I found few tips to improve the speed/performance of J Developer and documented here for my reference

1. Disable auto build on save

Tools -> Preferences -> Code Editor -> Save Actions -> Remove Build project on save(by Clicking on Save)

2. Change look and feel to Windows instead of Oracle theme

Tools -> Preferences -> Environment -> Look and Feel to ‘Windows’

3. Disable/Un-install updates which you are not using

Tools -> Features -> In Manage Features and Updates

Uncheck the updates which you are not using

4. In ide.conf file (located under Oracle home directory\jdeveloper\ide\bin)

AddVMOption  -Xms1024M

AddVMOption  -Xmx1024M

5. In jdev.conf file(located under Oracle Home Directory\jdeveloper\jdev\bin)

AddVMOption -Doracle.ide.osgi.buddy.delegate.resource.exempt.paths=META-INF/services/javax.xml.ws.spi.Provider

# optimize the JVM for strings / text editing

        AddVMOption -XX:+UseStringCache

        AddVMOption -XX:+OptimizeStringConcat

        AddVMOption -XX:+UseCompressedStrings

        # if on a 64-bit system, 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

6. Use Fast Swap Jdev feature to speedup the development
      Tools -> Preferences -> Run -> Weblogic -> Fast Swap

7. Use source editor for JSP and JSFF instead of design editor

     Tools -> Preferences -> File types -> Default editor

8. Also set high priority in the windows task manager as shown below
 
     Right click on jdev64w.exe -> set priority -> High



9. If you application does not use mds, locally you clean up contents of few folders in system directory on a daily basis. I see some bit of help by deleting contents of below folders daily. Do not delete folder itself. Just delete its contents.

.diagnostics , .history and .system cache
