How big server do you need if your traffic is 1K user at the same time

How big server do you need if your traffic is 1000K user at the same time.

And what about 100 users at the same time.

And what if your traffic is 10 million a month then what server you recommended?

It really, really depends on what your users are doing.

But there is no forum that has 1M simultaneous users - I bet there are only a few regular websites that reach those numbers.

How big server do you need if your traffic is 1000* user at the same time.

my mistake not 1000K but 1000 user at the same time or may be what about 10000 users at same time.

For assumptions consider it as a blog or forum. on blog user not have activity’s but on forum they does have.

8cpu + 8GB RAW server will serve 1000 users at the same time on wordpress blog or discourse forum?

It doesn’t look like a mistake if the title and post both say 1 million users. Anyway, you should change the topic title from “1M user at the same time” to “1K user at the same time” so you might attract someone with a similar load who could tell you what they are actually using. By the way, what is a “RAW server” - did you mean “RAM”?

Your assumption of a blog should be ignored because the forum should make higher demands on the server. But you still have to consider what users are actually doing:

  • anonymous vs logged-in
  • read vs post

There are a lot of useful topics about capacity and scaling in the #hosting category. Here’s two guess-timates that may be in the same ball park:

But above those levels, there is this site that was running on 8 CPUs and 16GB RAM:

What service level(s) are you aiming at? This post/topic is my favorite because it compares Discourse with traditional (i.e. LAMP-based) forums:

Don’t forget that if you are cloud hosting then the size of the database becomes more relevant because you might have to spend more money to expand limited storage.

FYI, here’s some further info which might be relevant to your decision-making options:

  • You can simulate capacity on a Discourse site and see what happens:
  • If you’re looking at costs then cloud servers are a lot more expensive than bare-metal servers:
  • Maybe you need to use a specific cloud host. This forum was moved to cloud hosting to cater for such requirements.

P.S. I hope that there will be a topic to help people with some general guidelines and real-world examples.

Based on Google Analytics real time report I can serve around 450+ concurrent sessions using our UpCloud.com 6-core / 16GB RAM VPS. They have one of the fastest servers around. But this is obviously a guesstimate, as GAnalytics is not the most accurate way to measure this, and the number of user activity (participating / logged in / guest) varies case by case.

We have this busy day only once a year and always the hickups have started to occur somewhere around the 450 sessions marker on GAnalytics. If the site starts to choke the number of sessions naturally drops rapidly.
