Yeah, I've been using AppCode for C++ on OS X for a while, and switched to CLion a week or so ago. CLion doesn't provide much more on OS X other than native support for CMake projects, but unlike AppCode I can use it on Linux as well.
No matter how time passes and how powerful desktop I use - java based software are just slow and bloat (especially IDEs). Even for some Java related work, I preferred to use JCreator (which is the only Java IDE purely written in C++ I believe).
I would say that's more down to IDE bloat, and nothing to do with Java. IDEs are often slow because they end up do huge amounts of indexing/static analysis, and/or have lots of plugins activated.
Well, I'm a heavy IDE user. On Linux I was on KDevelop (and now Qt Creator looks nice as well), on Windows mostly MSVC. I can't imagine working productively in vim and similar environments. But I still find Java based software/IDEs to be significantly slower and bloatware.
I know right? That 85M is a real drain on my 16GB of memory on my macbook, amirite? What year are we living in when people nitpick over native performance. Is vim too heavy because pathogen takes ten fractions of a second to load more than pine?
