This is my scenario
Model: MacBook Pro 15"
Model ID: MacBookPro2,2
Processor type: Intel Core 2 Duo
Processor speed: 2.16 GHz
Processors: 1
Cores: 2
L2 Cache (per processor): 4 MB
RAM: 2 GB
Bus speed: 667 MHz
Boot ROM version: MBP22.00A5.B07
SMC version: 1.12f5
MacBookPro:~ fabrizio$ echo $ARGYLL_REV_CACHE_MULT
1.1
MacBookPro:~ fabrizio$ ps -ue

One of the CPU is working at 100% all the time but the amount of RAM used
seems to be far from the limit set by ARGYLL_REV_CACHE_MULT.
