I switched to neovim for faster syntax checking with Neomake. Syntastic with vim was unusably slow.

I don't know if anything has improved with vim since (probably, with 8.0), but I have no reason to go back, either.

I got frustrated with how slow syntastic was too, but I have just upgraded 8.0 and have switched to using https://github.com/w0rp/ale for asynchronous linting and it's working very well.
