Is it possible it's a performance issue or is it my configuration?

[Invertisment]

If I have this chunk of code and press ds{ then it lags quite a bit until it finds out what to do. The cursor position is almost at the bottom (marked with [CURSOR].

I already disabled the highlighting but I'm not sure if it helped. Maybe there is some other tweaking that I could do? Or maybe it's my formatter

Probably it's my formatter.

It is nearly instant for me; the plugin leverages text-objects to find the corresponding pair (at least on main), so the deletion should be nearly as fast as va} is.
