I am not really familiar with that code, but comparision of the call graphs of "git log" vs. "git log -z", as produced by callgrind (shameless plug) and visualized by kcachegrind (again, another shameless plug) shows that the difference happens in log_tree_diff, called from log_tree_commit. While without "-z", log_tree_diff immediatly returns because "opt->diff" is 0, in the case of "-z", the tree differences are fully done even not used at all ?! The result is that "log_tree_commit" executes (inclusive callees) 340 million instructions without "-z", while it runs 2300 million instructions in the "-z" case.
