I have noticed that the first time I run pacman -Qdt after not running it for a while it can take a variable amount of time -- usually at least 20 seconds and as long as one minute. If I run it again shortly after that it completes in less than a second. Is there a simple explanation for this variation? I have 1705 packages installed and pacman -Qdt lists 26.
The reason I'd like it to be fast is that yaourt calls this command before a system update, so I get a 20-60 second lag before being prompted for my password for sudo pacman -Syu.
Because the second time, /var/lib/pacman/local/ is in your HDD's disk cache due to those files having been accessed so recently. But that much lag is pretty unusual. -- Eli Schwartz
