Hi folks,

I just landed a series of improvements to Gloda, so if you're running
nightly, your database should be rebuilt sometime today. Expected
improvements are database size reduction (I'd be interested in your
measuring before / after sizes), also, responsiveness improvements. We
should be able to witness all of that through telemetry, once the newer
version (with average values) lands.

Thunderbird 9 has telemetry.
Thunderbird 10 now has telemetry + gloda schema improvements.

By comparing the two, we should be able to figure out how much the
situation has improved. The newer telemetry dashboard should hopefully
allow for such things.

Cheers,

jonathan

By default telemetry is off - turning it on would help us a lot.

I have been pretty complacent about running various versions with a
common profile (Gloda turned off)
Am I correct in assuming that the data base will be rebuilt *every time*
I switch with Gloda turned on.

For privacy reasons, turning it on by default is not yet an option.
However, the "do you want to submit anonymous performance data" bar will
prompt everyone to turn on telemetry. The results have been pretty
encouraging so far.

This is a correct assumption. This is properly handled, and there is no
danger in doing so, except that it will indeed strain your system a
little bit while the initial reindexing goes one.

For information, I have posted a thread to asked to French users to turn it "on" in Geckozone forums.
see: http://www.geckozone.org/forum/viewtopic.php?f=4&t=96851

Hope it can help you to collect more data.

FYI, sizes of global-messages-db.sqlite before and after enabling
telemetry on daily (Mozilla/5.0 (X11; Linux i686; rv:10.0a1)
Gecko/20111025 Thunderbird/10.0a1):
Before: 8.9 MB
After purging: less than 3 MB
After re-indexing: 5.5 MB
