Yesterday (Nov 8) most of the buildbot master server was moved to an SSD. This makes the web interface much more responsive than before, so that it no longer takes many seconds to deliver a response even when builds are taking place.
A couple weeks ago (Oct 23) the Internet connection speed to the buildbot system was greatly increased. This allows the buildbot workers to download distfiles much more quickly, and makes transfers between the buildbot's private rsync server and the public one quicker so that even when the buildbot produces large binaries that need to be distributed, they can be transferred to the public server quickly so that updates to the ports tree are not significantly delayed. https://build.macports.org
