Sublime Text is very slow in certain operations …which is the extension causing the problem?
Assuming Earth, human settlement with electrical and supporting human resources. Fascinated enough to respond.
Binary poking about never works for me on Linux, that OS framework is just too chaotic. More luck on Unix, but has to be combined with rigorous wipe of Caches, Cookies, Saved Application State and Webkit. Cleanup as you move along. Interaction of installed packages with the system where data brokerage is not managed well (for all practical intents and purposes), is a nightmare… Consistently, having identified a problem package in a particular machine, it is then time to reinstall, avoiding the package and writing the package author… However, another machine at the same time may experience no problem with the package. So machine detailing is likely far more important than grumbling over spilled seed.
Perhaps even more problematic is snooping about for googly similars. Sublime text is powerful, because it does its own thing in the programming flow on your devices. No cloudy pollution. Everything that you do is always unique. Sublime package management is like gardening. Build a robust crop of essentials, and suit your diet accordingly.
