Generally, you should use a machine that has fewer users and is more lightly used.
The column 'users' gives the number of users logged in on a machine. The columns 'use 1min', 'use 5min' and 'use 10min' give the average load over 1, 5 and 10 minutes respectively. Smaller numbers indicates less usage.
