Benchmarking

Power usage

sys-power/powertop can guess the computer's current power usage in watts.

root # powertop
Power usage (ACPI estimate): 15.7W (0.5 hours)

CPU

Compiler performance

root # time emerge -1 coreutils

Output:

real    2m17.574s
user    1m46.572s
sys     0m53.450s

RAM

ramspeed

root # emerge -av ramspeed
user $ ramspeed -b2 -m4 && ramspeed -b1 -m4

Output:

INTEGER & READING      2048 Kb block: 5027.82 MB/s
INTEGER & READING      4096 Kb block: 4999.53 MB/s
...
INTEGER & WRITING      2048 Kb block: 2003.86 MB/s
INTEGER & WRITING      4096 Kb block: 1951.05 MB/s

Hard drive

hdparm

root # hdparm -tT /dev/sda

Output:

/dev/sda:
 Timing cached reads:   2318 MB in  2.00 seconds = 1159.52 MB/sec
 Timing buffered disk reads: 648 MB in  3.00 seconds = 215.92 MB/sec

dd

user $ dd bs=1M count=512 if=/dev/zero of=temp conv=fdatasync
root # echo 3 > /proc/sys/vm/drop_caches
user $ dd bs=1M count=512 if=temp of=/dev/null
user $ rm temp

Output:
