[pacman-dev] pacman -Qo takes a very long time

[solsTiCe d'Hiver]

hi.
so i just installed pacman 3.0.4 during my daily pacman -Syu. no pb libarchive 
and libdownlaod already installed

so the first command i run was:
pacman -Qo /usr/bin/versionpkg and it takes a avery long time !!! wtf ! during 
a compilation . so i stop the comilation and

i time it:
 time pacman -Qo /usr/bin/versionpkg
/usr/bin/versionpkg appartient à versionpkg 0.7.2-1

real    0m19.933s
user    0m17.049s
sys     0m2.316s

and with 100% cpu usage the last 10 second !!??

i run /var/lib/pacman in a tmpfs so the pb of the filesystem fragmentation is 
not a pb. 
so i tried without the tmpfs. 
the same.
i run pacman-optimize.
it takes 51s this time !?

now it's 19s again
