My discourse installation has been getting slower and slower and slower over the last few weeks. In the past when this has happened, rebuilding the app has helped. However, it doesn’t seem to help now. I’ve looked for advice on this forum, and tried some database optimizations (vacuum full verbose,…

[圖片] Fredrik Hubinette: Is there an easy place to find such stats? On the /about page, there’s a column for all-time. Looks like your machine hasn’t been rebooted for well over a year - probably worth doing that, and updating for security at the same time. It’s just possible the reboot will …

It seems that saving a post is particularly prone to timing out and fail. Not sure if that is any sort of clue as to what is going on though.

That vmstat output is telling us that - as things are - there’s not enough RAM. It could be that Discourse is working as it should, and all is as it should be, but that your data has grown to the point that 4G of RAM is not enough. Or it could be that something has gone wrong and a lot of RAM is i…

[圖片] Ed S: That vmstat output is telling us that - as things are - there’s not enough RAM. That’s on the point. If you can’t afford more RAM, you can try setting lower values for db_shared_buffers (say 128MB or lower) and limiting UNICORN_WORKERS to just 2 in the meanwhile, as you need to st…

[圖片] Ed S: One measure of size is to take a backup-without-attachments and see how big that is. 62.5 MB More RAM is fairly pricey from my hosting provider, so I will explore other options first. (And I’m worried that changing it will break my grandfathered-in pricing…) I changed db_shared_b…

[圖片] Fredrik Hubinette: What is the mini-profiler, and how do I use it? With an Alt+P on your keyboard, subsequent forum actions should put up a timing string just under the forum banner (for me, on the right) and if you click on the timing, you’ll see a popup window with some stats. [圖片] …

[圖片] Ed S: That’s about the same as mine, running with 1G of RAM. I have 2k topics, 15k posts, 500+ signups. Is there an easy place to find such stats? Most of the stats I see show me what happened in the last day or week, but no totals. [圖片] Ed S: What’s the history of your Discourse? …

I think I notice that your server is setup to use hypervisor whereas mine is setup to use lxc. I don’t know if that’s important. (My system shows a process /usr/bin/lxcfs which yours doesn’t, and yours shows a process hv_vss_daemon which mine doesn’t.) Also, maybe you could share output of df -T a…

1.3k topics, 24.7k posts, 631 signups, 7.1k likes rebooting linux machines doesn’t usually help anything, but I suppose I can try.

[圖片] Fredrik Hubinette: rebooting linux machines doesn’t usually help anything, but I suppose I can try. I agree with a skeptical attitude on this! But I don’t suggest it idly - I’m fairly sure we’ve seen a case of a long-running system which did improve with a reboot. (Edit: here , although …
