Kernel performance data for 2.6.14-rc4 is updated at:

991 patches went in for rc4 since rc3, all perf. results are
pretty much flat compares to 2.6.14-rc3. This is probably as
expected since kernel is in the quiet mode.

Result with fileio went up on IPF box, and it is because of a
intermittent bug in the mpt fusion scsi driver. A fix is
proposed [*] and we have verified that the patch improved
regression seen with fileio.

We are working on having a sensible configuration for dbench,
all numbers for dbench presented on the web site are taken with
default parameters, and it needs to be taken with a grain of
salt at the moment.
