1. From http://jimbob/trigger3.html, enter http://jimbob/jars/p_browser2.xpi
2. Click Trigger button
3. Click Install button from the confirmation dialog

Installation takes a long time (ie > 100% for Mac).  Check the install.log which 
contains some JS code to collect the install time.  Using older builds like M16 
does not exhibit similar behavior.  A table tabulating these figures can be 
found at http://jimbob/smartupdate/smartupdate_performance.html

No extreme degradation in performance.

Nominating for nsbeta3.

Compared to Beta1, the install engine now takes about 4 times longer on Mac, 3 
times longer on Windows, and 2.75 times longer on Linux.

Nominating for nsbeta2 -- installing browser-only on a Mac now takes 10 
minutes not counting download time. This UI regression has affected other 
parts of the product as well, and happened when nothing went into the 
XPInstall engine itself. I'm going to blame XPToolkits, although it could be 
the ender-lite stuff that went in over the weekend.

Don't see how the Toolkit could be causing this - why are you calling and 
engine slowdown a UI regression? Weren't other recent performance regressions 
due to string changes?  cc scc

The part that appeared to slow down was updating status text in our 
progress dialog. It may be string related, but it's behind the dialog APIs 
we're using.

I'm trying to get a Quantify run on it, but have been stuck in meetings all 
day. I have a run from before the slowdown I can compare to and will reassign 
the bug if I find a better home for it.

Hasn't that always taken some significant amount of time, especially on Mac? 
Can't we just cut it altogether? I doubt many users really care that we are 
installing *.shlb...

reassigning to pavlov

"I'm going to blame XPToolkit" doesn't quite cut it. Pushing back to dveditz 
until he can get quantify data that shows where the blame is. At that time, we'll 
be happy to take it if it turns out to be toolkit.

For a band-aide fix on our end, won't solve the basic layout/dialog slowness 
jimmy's numbers show.

Fixed, as suspected the dialog repainting was taking all the time. Now we 
update the dialog 4 times a second at most..

Performance is much faster now.  It's a dramatic difference.
