Ok. So I tried building the squeeze branch of T(A)ILS [1].
Here is what "time lh build" reports:
- in tmpfs :
real 9m31.897s
user 9m27.891s
sys 1m35.566s
- without tmpfs, on an encrypted filesystem over 2 SATA hard disks in
a RAID-1 array (please note the CPU is not so much used during most
of the build, so I doubt the encryption is a significant parameter
here):
real 64m18.963s
user 9m29.552s
sys 1m56.151s
Quite convincing, uh?
