This command took approximately 20 minutes of CPU time before downloading anything except possibly some NARINFOs. During this initial 20 minutes of CPU-bound activity, the only output was 4 occurrences of the following message: substitute: updating list of substitutes from 'https://mirror.hydra.gnu.org'... 100.0% The CPU time was roughly evenly split between the following two processes: --8<---------------cut here---------------start------------->8--- USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 8456 57.0 0.1 37420 7788 ?
