We can talk about that tomorrow. 2010/4/9 Ojan Vafai <[email protected]>
> Chromium has a bunch of perf bots that we run continuously. Most of these > are just page cyclers that loop through pages. They're grouped by different > types. You can see some graphs here: > http://build.chromium.org/buildbot/perf/dashboard/overview.html. The more > stable bots will also turn red on perf/memory regressions. > > This is really useful data that it would be awesome to have at a more > granular level than each time chromium pulls in a new webkit revision. Also, > it would be great to have this upstream so that it doesn't depend on > chromium engineers to notice and help run the tests. > > This came up recently due to a perf/memory regression from > http://trac.webkit.org/changeset/57215 on Mac loading international pages > (see > http://build.chromium.org/buildbot/perf/mac-release-10.5/intl2/report.html?history=150&rev=-1). > With that data we were able to find the root problem and have a path forward > for fixing it https://bugs.webkit.org/show_bug.cgi?id=37292. > > What would it take to support these (the ones that test web page perf) in > upstream WebKit? > > Some initial thoughts: > 1. Machines for the new bots. > 2. Make the page cyclers work with Safari (DRT?). I imagine this is not too > hard. > 3. Make the data available. Currently, these are on Chrome's internal svn > repo. I think this is due to fear of copyright infringement if we were to > publicly distribute them (i.e. a copy of someone else's copyrighted > website). I don't know the details here and IANAL, so I don't know how hard > this is to workaround. Seems like we ought to be able to figure something > out though. > > Any interest? Anyone willing to do the grunt work? > > Maybe this is a good topic for the webkit conference. > > Ojan > > > Abberviated #webkit discussion: > [11:29am] smfr: why doesn't webkit have data like that? > [11:30am] smfr: ojan: it sucks that such data are not available via > webkit.org > [11:30am] ojan: smfr: i agree > [11:30am] smfr: we should be measuring page load and memory use for every > build > [11:30am] ojan: smfr: no argument from me > [11:30am] dglazkov: smfr, ojan: we totally should. > [11:31am] Catfish_Man: mmm delicious delicious metrics > [11:31am] smfr: any volunteers? > [11:31am] dglazkov: I volunteer ojan > [11:32am] ojan: dglazkov: i unvolunteer myself! > [11:32am] dglazkov: then I volunteer smfr > [11:32am] ojan: but i fully support someone else moving these tests to > webkit > [11:32am] smfr: we need a good server-side hacker > [11:32am] smfr: that's not me > [11:33am] dglazkov: so would it be a matter of hooking up DRT to run > various tests and putting up a bot? > [11:33am] enrica: great project for an intern >
