dtrace discuss - Apr 2008 - Mozilla Dtrace and Tabs?

I use a lot of tabs and Firefox runs very slowly. I would like to figure out
which tabs are eating up resources (cpu, memory, etc).

Will the Mozilla dtrace framework be any help with this?

Hi,
> No one cares to comment?
I guess not many people know Mozilla DTrace. I had to google it''s page.
http://opensolaris.org/os/project/mozilla-dtrace/ announces this list as
a discussion place, but apparently no-one from
http://opensolaris.org/os/project/mozilla-dtrace/leaders does not
respond here.

You can get Brendan Greg''s and ?? (Alfred Peng)''s mail contact
from
the web pages, they should be able to help you.

If I try to look at their proposal
(https://bugzilla.mozilla.org/attachment.cgi?id=257958), I can not see
tab pages mentioned anywhere, so I guess that you won''t be able to
distinguish which tab does what. And if the JavaScript implementation is
still single-threaded, it won''t help you either.

But those are just my guesses I obtained from five minutes check of the
project. I might be totally wrong.

Sorry I could not help better.

Hi Ken,

You''re asking a question about the specifics of particular application.
You''ll
probably have better luck asking on a forum dedicated to Firefox support. That
said, DTrace almost certainly provides the facilities you''d need to
investigate the problem today. You can start your investigation a couple of
ways:

	look at what resources are consumed when you open a new tab
	see what functions are being called most frequently
	see where firefox is spending its time

One other thought here Ken is that you may want to have a look at a lab 
Angelo Rajadurai put together for JavaOne 2008 on DTrace.  It turns out 
there is a lot of non-Java content in it (it covers Ruby, PHP, MySQL, 
etc.), but there is a whole section on the Firefox DTrace provider.

I don''t recall if it addresses resource consumption, but just getting 
you started with the provider using some samples may be useful.

it''s fairly difficult to comment on something that has no context.

The last time I checked the Firefox dtrace probe status, they were source-only
(no usable binaries available).  I don''t know if that''s still
the case.

Absent any actual information, I''d say static probes would be a good
avenue to
exploe.

Hi Dan,

DTrace probes have been enabled for Firefox 3.0 nightly build:
http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/contrib/latest-trunk/

and also the RC1 builds:
http://releases.mozilla.org/pub/mozilla.org/firefox/releases/3.0rc1/contrib/solaris_pkgadd/.

When Firefox 3.0 is delivered into OpenSolaris repository, DTrace will
also be enabled.
