Hi all,
we have gotten lots of reports that it can take very long for MediaViewer
to display (unblur) the images (some people mentioned 20-30 second waiting
times); our tests and metrics [1], on the other hand, show 1-2 second
loading times. We need to find out under what conditions does the
application become so slow; if you experience something like that, or know
other people who have experienced it, please help us collect more
information.
Ideally, we would like to know the following:
- how long did it take for the image to load? (time spent between clicking
on a thumbnail, and the blurry image becoming sharp)
- can you reproduce the slow loading time with other images? (Use images
from a different wiki page, so that they are not preloaded)
- can you reproduce the slow loading time with same image, after refreshing
the page with a clear cach (Ctrl-F5 on most browsers)?
- what OS/browser do you use?
- what kind of internet connection do you use, what bandwidth does it have?
If you are comfortable with using the network tab on the web console of
your browser (F12 on most browsers), and can look at it and tell us in
detail which requests took up the majority of the loading time, that would
be even more helpful.
You can report the results here or on-wiki at [2].
Thanks in the name of the multimedia team!
