Agreed... And the statement that the server runs the cpu at half the post speed isn't correct. Rather, we could say that the observed workload resulted in half the performance per cycle on the T series tested versus the M series tested.
The older T series had a strong single threaded performance penalty. The newer stuff is a lot more flexible and can deliver better single threaded performance than a comparable M series.

filebench(1) User Commands filebench(1)
NAME
filebench - framework of workloads to measure and compare filesystem performance
SYNOPSIS
/usr/benchmarks/filebench/bin/filebench profile
/usr/benchmarks/filebench/bin/filebench -c stats_dir...
DESCRIPTION
filebench runs workloads to measure and compare filesystem performance.
Full documentation can be found at the performance community at: http://www.opensolaris.org
OPTIONS
The following options are supported:
-c stats_dir... Generates a HTML file (index.html) that is a comparison of the specified directories. stats_dir specifies the directory
or directories in which the results are stored.
OPERANDS
The following operands are supported:
profile Specifies the name of the configuration file ending in .prof. The configuration file specifies:
o what workloads to run,
o what parameters to run,
o the directory path on which to operate, and
o the directory path in which to store the results.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred.
2 Invalid command line options were specified.
EXAMPLES
Example 1 Running the Multi-stream Sequential Read Workload
The following example runs the workloads described in the configuration file named sqread.prof:
# filebench sqread
Example 2 Comparing Multiple Runs
The following example compares the results of two previous runs.
This example assumes that the results from the two previous filebench runs were located in the directories: /stats/wombat-zfs-noel-
Jun_27_2007-15h_45m_33s and /stats/wombat-ufs-noel-Jun_27_2007-15h_52m_11s.
This example generates a HTML file named index.html in your current working directory.
# filebench -c /stats/wombat-zfs-noel-Jun_27_2007-15h_45m_33s
/stats/wombat-ufs-noel-Jun_27_2007-15h_52m_11s
