speed.python.org has been updated to split out per-branch results for easier cross version comparisons, but looking at the performance repo suggests that the only 2.7 results currently reported are for the default UCS2 builds.

You're right, it's a bug, it's wasn't deliberate.

I fixed "performance compile": it now pass --enable-unicode=ucs4 to configure if the branch starts with "2.". https://github.com/python/performance/commit/9af0c6e029db9d2a8475f11d5cc601d...

I'm running benchmarks with this option. Once results will be ready, I will remove the old 2.7 result to replace it with the new one.

Note: Python 2.7 configure should use UCS4 by default on Linux, but that's a different topic ;-)
