We have around 12000 users. I have run discourse on a 2core 4g server for a month. And It has 30M bandwidth. I believe it should be enough. At first, it runs well. However, the server always shows 90% usage in the past few days. It usually takes me 4-5 seconds to open the latest page. I disable a…

12000 is a fair amount. How many page views a day? How many concurrent users? I’d at least double the core count.

Thank you robert! This is the page views. [屏幕快照 2022-08-20 19.03.50] I’m not sure about the num of concurrent users. :/var/www/discourse# netstat -an|awk '/tcp/ {print $6}'|sort|uniq -c 191 ESTABLISHED 16 FIN_WAIT1 7 FIN_WAIT2 2 LAST_ACK 7 LISTEN 2 SYN_RECV …

Oh wow, that’s a LOT of page views!!! Most by logged in users. I think it’s pretty obvious your two cores are maxed out. Upgrade your VPS to 4 cores if not 8. You have seriously outgrown this server. Do it fast to avoid losing your loyalty.

Oh, thanks! Our current vps is using Intel(R) Xeon(R) Platinum 8269CY CPU @ 2.50GHz (2 core) from AliCloud. Could you please give me any recommendation for cloud service provider?

Why not stick with Alicloud to begin with? Any problems with them? Do they offer a bigger server? Easier to migrate using same credentials and account. I love Scaleway personally but their locations in Europe may not suit you. (That said I have a lot of US users and you can always add a CDN)

You could also add a CDN if you don’t already use one: [画像] Should I add CDN despite my server is close to my users? Self-hosting Only way to find out is test slight_smile Not expecting any major advantages, but a CDN will reduce some of the load on your appl…

We need 4 cores/8 cores. AliCloud provide 4 cores vps with a price of 70 USD(monthly) :expressionless: and NO 8 cores plan. My alternatives are hetzner, contabo, netcup,greencloud (almost from Germany, and yes they provide with cheap prices) Have you ever hosted a discourse on their servers? Thank…

No but Hetzner is a great choice. Please checkout scaleway.com if you can host in Europe.

Here’s a 4 core with 500Mb/s bandwidth and 8GB RAM on Scaleway. [image]

Thank you! I’ll look at scaleway. Could you please tell me about your plans and the size of the discourse(about concurrent users etc.) as a reference?
