I think the markdown-preview plugin may have issues because once I get to about a 400-500 line file it pegs my i5 at 100% CPU and takes 5-6 real life seconds to enter a single character. This is on Linux. Other than that, I would say performance is reasonable on all projects I've worked with (couple hundred files in a folder while actively editing a handful at a time).
