The BuildLog wiki page is unwieldy. Bug 14101 will reduce the number of builds on the list, but I wonder if it would be easier to work with if the top level /BuildLog page was simply a table of contents and each build is a sub-page.
I don't know how the wikilog scales. I have instead made it "auto-archive" when there are 200 builds on a page, it creates and archive page and moves 150 onto that. http://git.yoctoproject.org/cgit.cgi/yocto-autobuilder2/commit/?id=9b210a7a2cafb65d0180c24b61e61781ae8d90d4
