> JetBrains - project was slow to open (+while indexing), but the IDE performs okay with 0.5 - 1 GB of RAM usage (though more needed when running/debugging) Just to be specific: Is this your experience just running the IDE at default settings, or did you increase the JVM heap size for it and had no effect? If you run it at default settings, the memory footprint will stay <1GB, because that's all it's allowed to use. My experience on this is that it's a great idea to bump the memory size to 4GB. I have not done any benchmarks on it, but it feels much faster in regular use. |

When the IDE is mostly idle (with 10-20 opened source files), it generally uses around 0.5 GB of RAM.
When i'm writing code, using autocomplete, reading documentation, running Maven actions, using the suggestions functionality (basically IntelliSense + some plugins), using refactoring functionality etc., then the memory usage can be bumped up to 1 GB.
When the code is running, the memory usage can get closer to the 2 GB limit, when using debugger functionality, recompiling classes on the fly and so on.
Personally, i haven't bumped the limit up higher, because i still need the memory for the actual Java processes of the services that i launch, since under normal circumstances i need at least 16 GB of RAM for all of the services to even run properly (but that may as well be a project related issue, since scheduled processes and a number of other optional things run locally, nor are all of them configured with Xmx and other parameters), though that's less relevant to the actual IDE performance (since i have swap turned off and it doesn't have an impact).
