89870 - Installer over Remote X excrutiatingly slow

Status: RESOLVED FIXED

(SeaMonkey :: Installer, defect)

From Bugzilla Helper:

When I run the installer over a remote X connection, everything is extremely
slow - it just took me over 45 minutes to install the latest nightly.  I know it
is not my connection to my server; all other apps, gtk, kde, and mozilla itself
once it is installed, run fine.  Also, the problem does not seem to be that the
installer is sending extraordinarily large amounts of X information, as I can
run other applications, even the GIMP, while installing.

Reproducible: Always
Steps to Reproduce:
1. Establish a remote X connection to some other computer.
2. Attempt to run the installer.
3. Go get a cup of coffee.

Actual Results:  Rendering of buttons, text, and everything else is very slow -
painting of the individual lines and rectangles is visible.  This creates a huge
problem during the actual install, as every time a file is extracted it repaints
the progress bar.

My connection is over AT&T cable and ping times to my X server are aprox 50ms. 
But again, this is not a problem for every other app I run.

I get this behaviour running the installer over X locally. Could this be the
same bug?

My guess is that the installer only polls the X server as often as it recieves
data, so using the installer on a slow connection, it is unresponsive. Comments?

Since bug 112618 makes installer the _only_ way to install nightlys, this
becomes dogfood for me (and I'm sure for a number of other people).

There's no way a SEA should take 45 minutes to install (that's what it takes here).

"silent mode" will avoid this problem.

./mozilla-installer -ms

you have to set the appropriate options beforehand in config.ini

This is fixed; the installer used to xsync, which made it ridiculously slow. 
The xsync call has been removed.
