The only other reason for poor performance - in case it was caused by A File Icon - I can guess from the available information might be the alias syntaxes, which are used to provide more icons. You could try to disable them via "aliases": false

If ST doesn’t get stuck anywhere while patching the themes, I doubt A File Icon can have any impact on performance.
