FaqMemoryReqs

What are memory requirements of NetBeans IDE?

The minimum memory configuration for the IDE is 512MB, can be quite reasonable for Java SE development of small to medium projects. The IDE can run with less memory, but UI responsiveness will be affected significantly.

The recommended memory configuration is 1GB and more, depending on any other applications running on the system. If you do Java EE development, large projects, have some application server or database running on your computer, then 2GB are recommended.

The IDE automatically determines optimal Java VM memory settings based on the size of physical memory. Rarely you might want to change the heap size.
