Use "--pretty=raw" for "git log" if you want to approximate "git rev-list --header". Or alternatively use the same "--pretty=format:" for git-rev-list. If you start using anything else, you only have yourself to blame. OF COURSE it's more expensive to pretty-format the messages. I get [torvalds@woody linux]$ time git rev-list \ --pretty=format:"%m%HX%PX%n%an<%ae>%n%at%n%s%n%b" \ --topo-order --parents --boundary --header \ --log-size HEAD > /dev/null real 0m1.596s user 0m1.556s sys 0m0.040s [torvalds@woody linux]$ time git log \ --pretty=format:"%m%HX%PX%n%an<%ae>%n%at%n%s%n%b" \ --topo-order --parents --boundary \ --log-size HEAD > /dev/null real 0m1.597s user 0m1.548s sys 0m0.048s so I'd say that with the same output, the timings are pretty much the same (except "git log" is more capable - "--log-size" does nothing for "git rev-list", for example). But if you ask for different formats, they'll have different performance, even if you then use the same command (ie "git log" will be slower than "git log" depending on the command line arguments!)
