I am using Sublime to edit files on a remote server over a very slow vpn connection. I was wondering if there was an option to disable the file monitoring? I don’t want it constantly polling the remote files I have open to see if anything has changed. Thanks!

There isn’t, but the only polling done out of the box is when the current file is changed, and that check is fully async. If you’re seeing some kind of blocking, it may be from a plugin.

OTOH, if you’re on OS X, then Cocoa itself does blocking IO in the main thread whenever the file is changed, to retrieve the current icon.
