p7 is not a slower CPU. the architecture is different than p5. the p520 is small compared to his new setup
did this ever perform well or is this a new issue? is it CPU bound, memory, disk, etc...?? we need more technical details to diagnose. check out perfpmr if you have not already. consider calling the people that did the setup.

NAME
cpufreq-set - A small tool which allows to modify cpufreq settings.
SYNTAX
cpufreq-set [options]
DESCRIPTION
cpufreq-set allows you to modify cpufreq settings without having to type e.g. "/sys/devices/system/cpu/cpu0/cpufreq/scaling_set_speed" all
the time.
OPTIONS
-c --cpu <CPU>
number of CPU where cpufreq settings shall be modified.
-d --min <FREQ>
new minimum CPU frequency the governor may select.
-u --max <FREQ>
new maximum CPU frequency the governor may select.
-g --governor <GOV>
new cpufreq governor.
-f --freq <FREQ>
specific frequency to be set. Requires userspace governor to be available and loaded.
-r --related
modify all hardware-related CPUs at the same time
-h --help
Prints out the help screen.
REMARKS
Omitting the -c or --cpu argument is equivalent to setting it to zero.
The -f FREQ, --freq FREQ parameter cannot be combined with any other parameter except the -c CPU, --cpu CPU parameter.
FREQuencies can be passed in Hz, kHz (default), MHz, GHz, or THz by postfixing the value with the wanted unit name, without any space (fre-
quency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000).
On Linux kernels up to 2.6.29, the -r or --related parameter is ignored.
