Linux package managers are slow
I measured how long the most popular Linux distribution’s package manager take to install small and large packages (the ack(1p) source code search Perl script and qemu, respectively).
Where required, my measurements include metadata updates such as transferring an up-to-date package list. For me, requiring a metadata update is the more common case, particularly on live systems or within Docker containers.
All measurements were taken on an Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz running Docker 1.13.1 on Linux 4.19, backed by a Samsung 970 Pro NVMe drive boasting many hundreds of MB/s write performance.
