rev-branch-cache: reenable memory mapping of the revision data Now that we are no longer truncating it, we can mmap it again. This provide a sizeable speedup on repository with a very large amount of revision for example for a mozilla-try clone with 5 793 383 revisions, this provide a speedup of 5ms - 10ms. Since they happens within the "critical" locked path during push. These miliseconds are important. In addition, the v3 branchmap format is use the rev-branch-cache more than the v2 branchmap cache so this will be important. On smaller repository we consistently see an improvement of one or two percents, but the gain in absolute time is usually < 10 ms. #### benchmark.name = hg.command.unbundle # benchmark.variants.issue6528 = disabled # benchmark.variants.reuse-external-delta-parent = yes # benchmark.variants.revs = any-1-extra-rev # benchmark.variants.source = unbundle # benchmark.variants.verbosity = quiet ### data-env-vars.name = mozilla-try-2024-03-26-zstd-sparse-revlog ## bin-env-vars.hg.flavor = default e51161b12c7e: 3.527923 ebdcfe85b070: 3.468178 (-1.69%, -0.06) ## bin-env-vars.hg.flavor = rust e51161b12c7e: 3.580158 ebdcfe85b070: 3.480564 (-2.78%, -0.10) ### data-env-vars.name = mozilla-try-2024-03-26-ds2-pnm ## bin-env-vars.hg.flavor = rust e51161b12c7e: 3.527923 ebdcfe85b070: 3.468178 (-1.69%, -0.06)
