I agree on this data point, but the discussion was long range compile time performance. There are many days in the past where compile time increase for a few days and then the problem is fixed (which is hopefully likely to happen here to). One thing to note is that Diego machine is a Pentium4 which is very sensitive to small changes in code generation (much more than Pentium 3 or Athlon), it might be better to build the daily GCC with -mcpu=pentium4 on such machines.
