Yes I have DEFAULT_TEST_TARGET=prove GIT_PROVE_OPTS='--timer' in my config.mak and run the test: 'make test >test-out 2>&1'. > I don't use that myself, though.

So, I have a perl script that can give me that info, like so: On Linux, (current master branch), the ten slowest tests: $ ./test-times.pl -n 10 test-out 1 22.269s t9001-send-email.sh 2 15.222s t7063-status-untracked-cache.sh 3 10.965s t9500-gitweb-standalone-no-errors.sh 4 9.978s t3404-rebase-interactive.sh 5 9.270s t3421-rebase-topology-linear.sh 6 8.099s t0027-auto-crlf.sh 7 6.056s t7112-reset-submodule.sh 8 5.937s t7610-mergetool.sh 9 5.711s t5572-pull-submodule.sh 10 5.229s t6030-bisect-porcelain.sh $ ... and those taking 10s or more: $ ./test-times.pl -t 10 test-out 1 22.269s t9001-send-email.sh 2 15.222s t7063-status-untracked-cache.sh 3 10.965s t9500-gitweb-standalone-no-errors.sh $ However, on cygwin (v2.13.0 test output file), the ten slowest: $ ./test-times.pl -n 10 test-out 1 385.057s t3404-rebase-interactive.sh 2 339.694s t3421-rebase-topology-linear.sh 3 224.854s t7610-mergetool.sh 4 211.230s t6030-bisect-porcelain.sh 5 180.297s t3425-rebase-topology-merges.sh 6 179.446s t3903-stash.sh 7 177.600s t9001-send-email.sh 8 175.278s t5572-pull-submodule.sh 9 160.422s t2013-checkout-submodule.sh 10 158.615s t1013-read-tree-submodule.sh $ ... and (some of) those taking 10s or more: $ ./test-times.pl -t 10 test-out 1 385.057s t3404-rebase-interactive.sh 2 339.694s t3421-rebase-topology-linear.sh 3 224.854s t7610-mergetool.sh 4 211.230s t6030-bisect-porcelain.sh ... 175 10.389s t4300-merge-tree.sh 176 10.324s t4213-log-tabexpand.sh 177 10.143s t3034-merge-recursive-rename-options.sh 178 10.108s t1410-reflog.sh $ [On linux a complete run is about 400s and on cygwin about 3hours!] ATB, Ramsay Jones
