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:
> [@With a server with 30GB of RAM How many users can I handle simultaneously](https://meta.discourse.org/t/with-a-server-with-30gb-of-ram-how-many-users-can-i-handle-simultaneously/35585/4):

> At that scale your server will be ample and over provisioned. A 4GB instance at Digital Ocean would probably be enough.

The site has been running very stable of a 1GB Rackspace cloud server, but now I am trying to figure out what would be the minimum requirements with this traffic for running Discourse at Digital Ocean. Old stats in Finnish: [Tappara.co](http://tappara.info/index.php?action=stats) Members: 1500, with 100 being super active Concurrent sessions: Can peak to 500-800 users online Traffic: Potential for 100k page views per 24h Posts: Thousands per month This is a fan forum …
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:
> [@Performance, Scaling, and HA requirements](https://meta.discourse.org/t/performance-scaling-and-ha-requirements/60098/8):

> Number of posts made is about the least interesting metric, even more so over such a long time period. Page views is far, far more relevant for determining needed resources. It can be a bit tricky to compare the requests and traffic patterns of a “traditional” mostly-server-generated forum to a Discourse forum, because Discourse is very API-driven, so we often serve multiple HTTP hits per “page view”, but we tend to service each HTTP request a lot quicker, so the forum appears to be a lot more…
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:
[https://meta.discourse.org/t/simulate-real-discourse-traffic/86818?u=remah](https://meta.discourse.org/t/simulate-real-discourse-traffic/86818)
- If you’re looking at costs then cloud servers are a lot more expensive than bare-metal servers:
> [@The Discourse Servers](https://meta.discourse.org/t/the-discourse-servers/5898/3):
>
> Performance wise there is no comparison; building your own modern servers is crazy fast compared to what you’ll get “in the cloud”.

- 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](http://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.

Hi,
I have multiple forums running on the same server with around 40K signed up users on these forums.
- Daily user access averages around a 1.5k to 2.5k users
- Daily views averages around 20k to 26k views
- Daily user to user replies averages around 3k to 5k
I am expecting this traffic to go much higher in future.
I have DB and Redis running on a separate servers
All servers have 4GB of RAM assigned to them.
Could someone give me a rough estimate of what kind of resources will be adequate this kind of traffic ?
Thank you
