07:37 <zapb_> Gerrit is again unusable ... :-/

09:40 <PaulFertser> zapb_: hey. It seems to be working now. Probably the right idea would be to use another VM for jenkins...

18:23 <zapb_> PaulFertser, what's the problem? is our server not powerful enough?

18:24 <PaulFertser> zapb_: I'm not sure, I could never catch it in (mis)action

18:25 <PaulFertser> zapb_: the jenkins builds are already niced and quite limited so there should not be any influence on Gerrit.

18:25 <PaulFertser> zapb_: there was a problem when jenkins itself was hogging CPU really hard due to some old metadata, I should probably delete it again, it was the only workaround that jenkins officially proposed.

18:25 <zapb_> PaulFertser, what hardware do we have at the moment?

18:27 <PaulFertser> zapb_: it's not a dedicated server, it's a VM at Mythic Beasts. I can look up specific configuration later.

18:28 <PaulFertser> Single core, 2 GiB RAM.

18:29 <zapb_> Because Gerrit seems to be quite slow in comparison to my GitLab instance

18:31 <PaulFertser> https://plugins.jenkins.io/git/#remove-git-plugin-buildsbybranch-builddata-script is the weird thing :/

18:32 <zapb_> PaulFertser, but we are running Jenkins in the same VM, right?

18:32 <PaulFertser> Yes

18:33 <PaulFertser> This build data makes jenkins itself run some thread which hogs CPU like mad for many minutes.

18:33 <PaulFertser> Cleaning it now.

18:34 <zapb_> Okay, my setup runs on dual core with 8 GiB RAM

18:34 <zapb_> Maybe we should upgrade the hardware or at least move Jenkins to a different VM

18:57 <PaulFertser> I just run the script to clear Jenkins jobs, it helped a lot the previous time.

19:11 <zapb_> PaulFertser, sounds good but still it seems that we're operating just on the edge, no?

19:35 <PaulFertser> zapb_: kinda yes. Please complain when it's annoyingly slow again.

19:36 <PaulFertser> zapb_: I'm not the one to decide about getting another VM for the project but if we really see the need I think we will get it. Or probably put jenkins itself in some really limited cgroup.

19:37 <zapb_> PaulFertser, sometimes it is sufficient to switch the provider, depending on what we pay at the moment

19:38 <zapb_> But probably it is the best solution to move the CI to a different (maybe even a bit more powerful) server / VM

19:38 <PaulFertser> I have an impression Mythic Beasts is really the best. They have really superb tech support and also they give us more resources than we pay for.

19:39 <PaulFertser> They have a blog post where they explain how they have their leading tech engineers take shifts doing tech support.

19:45 <zapb_> PaulFertser, not sure, it seems that we pay 7 GBP (~ 8 EUR). For 6.37 EUR I get a dual core VPS with 4 GiB RAM

19:46 <zapb_> (just as an example)

19:49 <zapb_> However, we should definitely avoid scaring developers away by failures etc.

19:51 <PaulFertser> zapb_: I agree we should. They need to speak up, I'm trying to act accordingly fast.

19:51 <zapb_> PaulFertser, sure, thanks for the administrative work!
