intellij_performance_settings
Intellij IDE configurations for high-performance. VMoptions and properties files are directly usable in the IDE, assuming your hardware can handle it.
- To add to the IDE: Help -> Edit Custom Properties / Edit Custom VM Options
More Performance tips:
System
- IDEA is heavily IO-bound
- Do not store sources, caches or system directories on network drives
- Disable antivirus scanning for system directory
- Regularly run disk defragmenter
- Turn off Windows System Restore
JVM
- In –server mode, increasing –Xmx helps IDEA’s caches live longer
- Parallel GC helps on multicore machines but may cause stability issues
IDE
- Use latest version
- Disable unused plugins
- Exclude unneeded folders
- Set version control to None for generated code
- Avoid large number of unversioned files
- Do not disable “Synchronize files on frame activation”
- Switch Project view to “Project” rather than “Packages”
- Disable expensive inspections
- Disable framework-specific validation on Make
- Do not use method breakpoints
