Hi,
I tested Guillem's command on my own system and got:
~11.5s (cold cache/first time)
~0.3 (warm cache/2nd+3rd time)
For reference, "dpkg -l | wc -l" says I have roughly 1500 packages
installed.
I do not know what the original numbers were, so I cannot put the
following numbers into that context.
Thanks,
~Niels
