Slow (2 hours) for 7000 targets

[jjh42]

Hi,

I'm not quite sure how to get a simple reproduction. In our repo (bazel 7.1.1, bazel-diff 7.0) when we have a large number (7000) targets change (due to e.g. changing a build flag) then bazel-diff get-impacted-targets step takes 2 hours to complete.

We are running a setup very similar to the example script in this repo.

I'm just wondering if you had any pointer how we could try and determine what's going on. From other comments, I don't think this is expected.
