The most frequent consumer of the historical data is webkit-patch, which uses it to map from revisions to builds: http://trac.webkit.org/browser/trunk/WebKitTools/Scripts/webkitpy/common/net/buildbot.py#L109
It's used when we're walking back through revisions trying to find when the build broke, or when the user passes us a revision and expects us to know build information about such. It's possible we could move off that map with some re-design. One thing which would *hugely* speed up webkit-patch failure-reason (and sherriff-bot, and other commands which use the build_to_revision_map) is if we could make the results/ pages paginated. :) I would be nice to keep all the build data for forever. Even if after some date in the past its on a slower server. -eric On Sat, Oct 16, 2010 at 12:38 AM, William Siegrist <[email protected]> wrote: > On Oct 14, 2010, at 10:13 AM, William Siegrist wrote: > >> On Oct 14, 2010, at 9:27 AM, William Siegrist wrote: >> >>> I am in the process of moving buildbot onto faster storage which should >>> help with performance.
