* Perfathon update
* Perfathon update
** vlad failing to provide data
** vlad has data
** vlad will do so by next wednesday, because even if I had started uploading useful data the upload probably wouldn't have finished by then (sorry!)


* pageload test rewrite ([https://bugzilla.mozilla.org/show_bug.cgi?id=387110 bug 387110])

* probe update
* probe update
** vlad spoke with Sun guys
** stan taking over mozilla/gecko side of probe work
** will work with them to integrate XP-probes and dtrace probes into (most likely) a new toplevel module
*** will get Sun's dtrace patch as well as xp-probes checked in to new toplevel dir, then work on merging the two
** then will present to module owners and show demos
** crowder taking spidermonkey side
*** hopefully can convert per-module tracing schemes into probes
*** will be dtrace only
*** Sun guys would be happy to come out and do a presentation of dtrace-in-mozilla and give an idea of what can be done with dtrace itself and the scripts
** module owners should let stan know if they have any situations that they'd like to analyze, so that he has more information about how to structure the probe work.
** dtrace should probably be on by default in our builds if dtrace is possible
*** for example, examining loading from network performance vs. loading from disk
*** not sure about OSX -- can we build with dtrace enabled and still run on 10.4?
** Sun guys will be here on Aug 30 to do a presentation on dtrace, followed by hands-on work with a smaller group of engineers
** xp probes should be off, but possibly on in our tinderbox/nightly builds
*** vlad to investigate perf impact
