If you haven’t tried the latest version of IntelliJ IDEA yet, there is at least one important reason to do it. While most of the excitement around the new release has to do with Darcula, the new dark look and feel, the most thrilling feature of IntelliJ IDEA 12 is its brand new compiler.
As we mentioned earlier, the new compiler is much faster and provides new options that were previously unavailable.
On the chart below you can see a comparison of compiler performance in IntelliJ IDEA 12 and IntelliJ IDEA 11. In this test we have measured the time of a complete rebuild of IntelliJ IDEA Community Edition project. As you can see, IntelliJ IDEA 12 is more than twice as fast as the previous version.
