Our Discourse site has more than 10k users and about 700 daily engaged users. users sending an average of 10k posts per day. our community has more than 160k pageviews/day including crawlers and anonymous users. Almost all of our users are connected to us via mobile devices. We ran community in sta…

Thanks @marianord , Unfortunately, we do not use CDN. The upload rate in our forum is not very high. Most of the time, users talk about various subjects. For example, in the last year, we had about 2.8 million posts and 2.7 million likes, but only 25gb of files are uploaded. Do you think that accord…

I disagree with @marianord . I don’t think that a CDN would make a noticeable difference with respect to the load on your server. These are just static files and they are not heavy to serve at all.

CDN and S3 are two different things. S3 offloads the files and backups to another server that is managed by a cloud provider (really high level summary) CDN caches the statics files of your server (images, JS, CSS) to server from multiple servers (PoP) around the globe to speed up the loading of t…

[изображение] marianord: you’re reducing the amount of requests that get to your server therefore reducing the load A request for a static file does not have a large impact on the overall server load. The requests for dynamic content are the heavy ones. [изображение] marianord: It’s a lo…

True, but Discourse has a few exceptions, like stylesheets that are served by ruby, so having a caching CDN means those requests doesn’t use up the unicorn processes. Regarding the OP problem, the first thing needed is having someone knowledgeable do some performance analysis during peak hours and …

[изображение] RGJ: Why are you talking about json files in a CDN context? I’m saying that the JSON requests will hit the server, the static ones won’t.

Thanks for your guidance, until a few months ago we used the Cloudflare CDN service and made good changes to the static content through the page rules. After it, I read somewhere that using proxies like Cloudflare drastically reduces the performance of the discourse, so we disabled it. Yesterday we…

This may be older information, but I do recall reading that discourse prefers a lower number of more powerful CPU’s vs a higher number of lower powered ones… even if you update the number of unicorn workers. @codinghorror , can you confirm if this information is still accurate?

Yes, that is correct, core CPU power is important, but it improves overall speed. @nildarar is having a performance bottleneck and that needs a different approach.

Are there any special tools for identifying discourse performance bottlenecks? [image] htop screen sorted by CPU usage Our forecast is that next year the number of our users will triple, so from today, we must provide the necessary resources for this scale.
