Each graph displays benchmark results relative to its baseline commit, which is the latest stable release (e.g., 1.18.3) at the time of testing. The 95% confidence interval is displayed in light gray. On hover, the graph displays the benchmarked commit at that point (click to view full commit).
Note that some commits are not tested, so there could be
multiple commits (not shown) between two points on the graph.
See the linux-amd64-perf column on the
x/benchmarks build dashboard
for tested ("ok") / untested (empty) commits.
The 'branch' selection above is the Go branch that benchmarking ran against on the build dashboard, not the subrepo branch.
Using the 'unit' search box above leads to a page that shows much more detail about each individual point in the selected time range. Another way of reaching this page is to click the unit name that acts as each graph's title, i.e. "sec/op".
