Continuing the discussion from Docker using a lot of CPU : [image] Docker using a lot of CPU > Looks like one should be rather conservative in upgrading docker? Being conservative in upgrading docker isn’t even enough; we follow that policy (still on 17.06), and we still got hit by a ripper of a…

Is 17.06 still the recommended? We’re on 17.10.0-ce ourselves. If you’ve installed via apt it’s relatively straightforward, uninstall, reboot: sudo apt-get autoremove -y docker-ce \ & sudo apt-get purge docker-ce -y \ & sudo rm -rf /etc/docker/ \ & sudo rm -f /etc/systemd/system/multi-user.targ…

Usually the difference is observable from whatever server management you use, we’ve got everything in either AWS or DO and most of it is hooked up into New Relic. If there’s a performance difference there’s also usually an observable step up or down in CPU usage. We’ve not gone so far as to look at…

Well, @mpalmer seemed to think differently, and he seemed to suggest that that is not what you’re doing: [image] Docker using a lot of CPU we follow that policy (still on 17.06) But okay. So my question then is: is there still a reason not to use the latest version?

Yes, I understand. I was just wondering whether such reasons currently exist.

I’d interpret that as “specific reasons that your installation of Discourse is different from ‘Most’ installations of Discourse”. Or “you should already know if this applies to you” or “your sysadmin said you need to hold back the upgrade” or …
