you can also measure the times it takes to check the size of the
dir... for example i am using an automatic backup for the pacman
database when playing with things and this happens by copying just
the whole folder to another folder. here some details - after not
running pacman-optimize for about a month time:
[EMAIL PROTECTED] ~]$ su
Password or swipe finger:
[EMAIL PROTECTED] damir]# drop-all-caches
:: Dropping Caches [DONE]
[EMAIL PROTECTED] ~]# time du -s /var/lib/pacman/
75876 /var/lib/pacman/
real 0m12.121s
user 0m0.350s
sys 0m0.717s
[EMAIL PROTECTED] ~]# time du -s /var/lib/pacman-backup-20071003/
75876 /var/lib/pacman-backup-20071003/
real 0m10.723s
user 0m0.150s
sys 0m0.637s
in my eyes, it is not a significant difference. but it helps extremely
when done over a longer period (years).
