This is grammar specific, \cc @the-mikedavis

Just to double check, you are compiling helix in release mode via cargo build --release right?

I compile it in debug mode and I've tried the release version, the same issue exists.
The result of perf report is collected from debug version.

The diff file can be generated in the helix repo.

git format-patch --stdout v0.4.0..v0.6.0 > test.diff

Thanks, that helps! I can reproduce it and it seems to affect typing afterwards as well.

This might fall under #338? I can reproduce the lag by making a similarly large rust file

$ cat $(ls -t **.rs) > f.rs
$ ls -lh f.rs
-rw-r--r-- 1 michael users 2.7M Mar 25 08:22 f.rs
$ wc -l f.rs
62196 f.rs

There might be some improvements to tree-sitter-diff we can make to reduce the number of named nodes but I doubt it would be a noticeable improvement for very large files like these.

I don't know how treesitter operates exactly, but wouldn't streaming bits of the file to treesitter solve the issue?
