Since this is glaringly inconsistent with the timings Alan published, I think it would be a good idea to measure the difference for each of the*.el files, because it could be that a couple of outliers skew the entire picture. That is, put the 'time' command inside the 'do', and don't use -j8; then compare the outputs.
