probably power management. Under light loads it automatically scales down your 
cpu clock to preserve energy and make sure the noisy fan doesn't kick in. 

In /sys/devices/system/cpu/cpu0/cpufreq you will find some files about the cpu 
frequency. cpuinfo_max_freq should be the 1.66 Ghz. You can change the 
governer in scaling_governor (just echo performance > scaling_governor) so 
change the content. You can also play with the cpuspeed daemon 
(/etc/cpuspeed.conf) to change the settings.
