What are we using to measure these improvements? What is the -turbo lib being used for?
We use tjbench to measure the improvements. The browsers (firefox/chromium) is a use case mentioned on the roadmap but I didn't have seen any results. Tom knows more.
Debian/Ubuntu P are going to move to libjpeg8 by default making current package obsolete in the future.
Note that when we asked Darrell about this he questioned the performance benefits of version 8. Mans probably knows more. At any rate, -turbo as an upstream is the only sane decision.
Who is making the choice from the Ubuntu side -- and is there a bug open for this?
Bill Allombert is libjpeg Debian maintainer. At the moment, Ubuntu is following Debian. There isn't any bug open as the transition didn't started yet.
I think Tom and Ricardo should probably talk to Bill about it; I see this as being a very questionable move. I'd much rather move to seeing libjpeg deprecated into a libjpeg-legacy-8b package for good and -turbo become the actual system version.
