Some Significant Improvements
Saturday December 11th, 1999
M12 is right around the corner, and will boast significant improvements in the responsiveness and layout rendering times of the application.
First, Dave Hyatt has checked in some changes which do "memory recycling of all layout frame objects". This recycling seems to be the cause of significant improvements in the responsiveness of the UI. In #mozillazine, I heard "nearly as fast as 4.x" (on a P90 with 16M ram; I think that it's as fast or faster than Communicator 4.x now, at least on my P2-450). Menus and context menus now respond smoothly and quickly, the sidebar expands and contracts quickly (albeit with some bugs, still), and new windows pop up much faster than before. These improvements have been noticable on Windows, Linux, and Mac platforms, but to different extents. You will just have to try downloading a build for yourself!
Next, Vidur Apparao added changes that allow you to tune the incremental reflow. A number of people complained about how the incremental reflow changes of M11 were a good idea, but they were interfering with UI responsiveness as a page loaded. These tuning options address that problem, but even more improvements are expected after the M12 release. To try out the tuning for yourself, download today's build (December 11), and then follow the instructions on the next page (click "Full Article..." at the end of this news item). These options are only for people who are comfortable editing preference files. If you're not one of those people, these options should be enabled automatically at M12's release, so you'll be able to try it out then.
I would suggest picking up today's build when it's available (December 11), as it should contain a fix for alert-box buttons that you'll want to have. You can get the latest build from our builds page, or the nightly builds directory.
Remember, as always, these builds are not for the casual user. None of the software is guaranteed to do what you expect. MozillaZine makes no guarantees about the stability of these builds. Download at your own risk.

Keep in mind that milestones are really just a sort of checkpoint. The goal of a milestone is to pause just long enough to see what you really have. Development on M12 is pretty much wrapped up. I think that M12 is branched and in a "clean-up" phase and M13 work will begin today (I may be wrong, feel free to correct me if you have better information.) So if you grab a nightly M12 build from today or yesterday, you're probably getting a very close approximation of what will be called the official M12 release (note: the morning windows build from the 15th and the evening windows build from the 16th are pretty solid). But if you're like me and you need to be on the bleeding edge (and you don't mind spending 30 minutes to download a build that may not work) you'll be grabbing that first M13 nightly.
