> There are quite some cache misses on the local diff-cache when there are external changes because the TieredDiffCache first checks the local diff-cache. The majority of calls can indeed be served from the local diff-cache, because local commits are usually more frequent than external changes that come in once a second. The cache misses could be avoided if there was a hint what kind of change the diff is based on.
