Our community has high traffic spikes based on real world events. Ice hockey games to be exact, that result about 1000 messages to a dedicated topic in about 2,5..3 hours. As discussed in another topic , we have trouble dealing with the spikes. This has lead me into prospecting other hosting options…

You’re right it’s old posts but the trend seems consistent :thinking: [image] Slower Dedicated Server vs Faster VPS None of this really matters (past a certain low point like 2GB RAM, 2 cores, unless you have an enormous database), what matters to Discourse is single threaded performance . Ho…

It’s hard to provide guidance without knowing exactly what is the current bottleneck you face. Using Prometheus exporter plugin for Discourse can show exactly what of the many components is the problem.

Even though I introduced our case in the OP, the intention was to discuss this on the generic level. I may be on the hosting market in the mid-term future, regardless whether I have our root case identified or not.

For Discourse, you should favor fast cores over more cores. If you can get both, that’s even better (for load scenarios). But in the typical case, 2 fast cores will do better overall than 4 slow cores. We tend to measure this in build time, here are some examples . But any single threaded benchmark …

I’m no expert on the subject, but I’m not sure the virtual cores of a VPS are comparable at all to physical cores of a CPU. I guess that to have a broad approximation, you could look at the amount of RAM offered, and assume they run these VPS on a 256 Mo computer. Contabo with their “10 (virtual) co…

[image] ljpp: For just 42€ you can get a dedicated box from Hetzner, with Ryzen 5 3600 CPU. As I was looking at this offer; and thinking :face_with_monocle: hum good deal, I saw that the RAM wasn’t ECC, so quick search on the web, and what pops up ? this blog article by Jeff :sweat_smile: Th…

Oh wow, I’m already hosting with Hetzner but at a higher price point with a slower CPU & less storage than their current Ryzen boxes. This makes it very interesting to switch… thanks for the note!

Thank you for the blog link. That is a good read. I also agree that video is worth a thousand words and well… also very funny.

Has anybody done some tests with different CPUs regarding the size of L3 cache? I’ve seen some mentions that Ruby is very demanding for memory . That could give a hint about possible impact of CPU cache size, because Discourse works with large datasets. I’m deciding on new server and choosing the r…

A lot of CPU cores or fast cores?

In my experience that will not make a significant difference.
