Last week was the first of some Launchpad Performance Weeks that we’re embarking upon. The Soyuz team worked hard on improving the performance of the PPA page, which had a tendency to be very slow or even time out on PPAs that have a lot of binaries published.

The more observant of you will have noticed that the PPA page on edge is now using asynchronous requests to fetch both the “Repository disk usage” section, and the package information section that is expanded when you click on the triangle at the left of each source package row. This means that the initial page load time is a lot quicker! There’s still some more speed we can get out of the page by reducing the query load that it places on the database server, and we’ll deliver that change soon.

We also fixed a smaller snafu — as part of the webservice work that we’re doing, we managed to accidentally enable a URL that let you view the main Ubuntu repository as if it were a PPA page. These links nearly always timed out because of the size of the Ubuntu archive, so that URL will now redirect to the /ubuntu page on Launchpad instead.

Also in the pipeline is a major overhaul of the PPA page. Watch out for that soon!
