Really bad performance on very large lines


I have a JSON files with a very looong hex string as some values. By saying really long, I mean that it’s up to 50k chars. So when working with this files it’s pretty often that Sublime Text just hangs for about 10 secs with 4 cores 100% load. As I figured it out it’s highly likely that Sublime are just saving session at that time.

So in general Sublime comes pretty unusable for those kind of files, as again as I figured out saving session happens pretty often.

So is there any way to avoid such session saving in background for a given files?

Assuming you’re using a recent version ST will log in the console when session saving takes longer than normal.
