i am working on several projects at once, one is my starcraft ai. in terms of project size, i am not sure what to count, so i'll give you the compilation times ;)
AI: ~45 seconds
real world project/at work (consists of multiple sbt projects): about 5 minutes
in my ai project, the plugin is very fast, i never have to wait. for the big project, i *usually* can work without waiting for the ide on my machine at home (4.6ghz 6700k) more than a few seconds even in what i imagine to be a complicated scenario for code completion. at work i only have a notebook (two actually, haswell, 2.7ghz & 3.5ghz) and those are *significantly* slower, the 2.7 one noticeable more than the 3.5 one). the felt speed is 25% of my desktop machine on the slow one.
is there a big difference between mobile and desktop cpus, apart from the clock speed? is skylake just better at compilation/compilation like tasks/what the scala plugin is doing? i use copies of the same VM on all machines, all use windows 10 outside and ubuntu 14 inside, so the software should not be the cause.
