Subject Re: Live testing of SF download mirrors
Date Wed, 18 Apr 2012 12:45:09 GMT
Hi all,

we have been testing AOO downloads for about 10 days, below our findings:

- downloads per day ( )
- info about geographies ( )
- operating systems ( )

We spent the first days to tune our delivery system and facilities to
serve AOO downloads, We actually started by putting a CDN in place
that could grab files from our master mirror as its origin server, and
we learned we needed to pre-cache files to speed up downloads. Once
CDN was working properly, and we got those test results we updated the
test to servey we eventually switched to serve up these files from our
normal mirror network. As of today we updated also the download page,
now reporting the information formerly delivered by the download page
at Apache (e.g.

Our understanding based on the above data, and the expectations set by
the community prior to the test is that we are not serving all
downloads, (e.g., automatic updater
downloads, etc) and it's unclear how many downloads are actually
served by different pages. We should probably try to route all
download traffic, so that we can provide more accurate download stats.

We have tested our expanded mirror network, and burst CDN capacity,
and are confident that we are well positioned to serve much heavier
download traffic than is expected at release time. Since the traffic
will be high also be high for updates, we might take additional
precautions and continue to route auto updater downloads through
MirrorBrain, and use Apache and mirrors as a backup.

To the extent that is the primary recomended download
source for AOO downloads we feel it is important to keep providing the
PPMC with accurate stats info (see above), also via API, as mentioned
before (see If there is more download
statistical data that the PPMC would like to see, please let us know
so that we can try to meet those needs.
