So far systemd.LinkUnitFiles() has been called with the force option turned on. That was one of the reasons of performance issues. Let's introduce an option systemd_link_unit_force, false by default. Users can set the option in fleetd.conf. That option will be passed directly to systemd.LinkUnitFiles().

What's the actual reason for the bad performance? |

@jonboulle According to a report(#1393 (comment)), it's because systemctl link is being executed for each unit. I think the topic was also mentioned in the talk by @hectorj2f at the last CoreOS Fest. |
