I have been building my OS X builds of BlueGriffon on the same OS 10.6.5 desktop i7-based machine for the last two years. Two years ago, the i386 part of the universal OS X build of BlueGriffon was taking precisely NINE minutes and 45 seconds (yeah, quite fast) to build from scratch, without ccache, with a -j8 flag.
Today, a build of BlueGriffon based on a very recent pull of mozilla-central on the same machine, same OS, same HD, same CPU, same -j8, same build options, ccache disabled, takes TWENTY-NINE minutes and 13 seconds...
So I have a very naive question: can someone explain me here in the comments why the time needed to build Gecko on a desktop has been multiplied by almost exactly three in these two years? Please no flame, this is not a rant but only a technical question and I would like to understand better; thanks.
