Optimal Settings For Presentation Only Compilation

I'm working on a very large scala codebase that uses a custom build tool for compilation. I use intellij only for its presentation compiler. How should I configure intellij in order to run as quickly as possible? Should I turn on "Use external compile server for scala"?

Unlike Eclipse, IDEA doesn't rely on Scala compiler for static code analysis, so compile server has nothing to do with highlighting. If you rely on the external tool to compile the project, it's probably better to turn off the compile server.

You may try to tune IDEA / JVM performance in general, for example, by using server JRE and by increasing heap size, more info:
