Rebase conflicts can sometimes be harder than merge conflicts. This is because merges look only at the end points (what you have, and they have, and the merge base). But the rebase will look through each commit of the rebased topic. This can manifest itself in two ways:

You'll get more conflicts in two stretches of code that reach similar endpoints, but get there through differing paths. For example, consider this trivial example:

$ echo base >file && git add file && git commit -m base

This repository has a very large number of refs, which shows some slow-down on certain git operations.

This is a repository that has been packed over time with "git gc", but repacks from ~245M to ~145M with "git gc --aggressive". To narrow it down, I tried different packing options. With each of the following commands, I get these resulting pack sizes:

git repack -ad: 246M
git repack -ad -f: 376M
git repack -ad --window=250: 246M
git repack -ad -f --window=250: 145M

	# them, in addition to the tree storage itself. All sizes are in bytes, and
