I noticed that cpu MHz in /proc/cpuinfo is wrong: processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Genuine Intel(R) CPU 3.80GHz stepping : 6 cpu MHz : 948.218 cache size : 2048 KB fpu : yes fpu_exception : yes Dmesg also says: PID hash table entries: 2048 (order: 11, 65536 bytes) Xen reported: 948.218 MHz processor. Console: colour VGA+ 80x25 Dentry cache hash table entries: 65536 (order: 7, 524288 bytes) Also $ time sleep 3 real 0m15.042s user 0m0.000s sys 0m0.000s I'm sure it used to be correct, i.e. close to 3.8 GHz.
