Is it windows? I'm on windows too and it feels like it takes forever to load.

According to the console:

plugin init time: 0.726977 loading bindings loading pointer bindings found 1 files for base name Default.sublime-theme theme loaded app ready pre session restore time: 4.48531 startup cache, total files: 94 cache hits: 94 startup time: 4.62067 (package setup was not run) loaded 837 snippets

So indeed around 5 seconds to load.

I'm using all default stuff apart from choosing a different theme. My machine ins't SSD but is up-to-date otherwise.
