Also be aware that floating point (VFP) performance on ARM cores can vary somewhat dramatically, usually based on general register to NEON / VFP register transfer costs.

and testing, I appreciate it as always.

It looks like only bzip2 ran for long enough to make a valid comparison.  I'd be interested in reproducing any of the benchmarks used here:

Here are figures from a gtkperf run (both with 64M graphics memory).
