I was never able to know this detail, I always found approximately data.
How much RAM, CPU Cores, and Bandwidth do I need for every user?
Which is the formula?
For example, how many resources do I need for support 250 concurrent users?
I don’t think is a negligible data, cause if you buy a weak VPS, I guess that ts3 server will crash.
At the other side, if you buy a too big VPS, you’ll waste lot of money.
Here you can see all the minimum requirements for a TeamSpeak 3 Server
Teamspeak Server itself isn’t verry big and doesnt need much resources
On a TS3 server with 128 Clients and more than 500 users connected (not all at once) The installation + sqlite-database-file + uploaded avatars is round about 72 MB of disc space size.

Yeah I found this page, but as you see it’s not so specific, I mean, it say:
- For the CPU: SSE2 capable CPU (yeah but how much power per client?)
- For Memory: This depends on the operating system being used, however a minimum of 1 GB RAM is recommended. Total memory usage depends on the number and size of hosted virtual servers. (ok, so how do I know how much RAM do I need for example 250 users connected all at once?)
- For the Hard disk: The bare minimum installation is 15 MB. (here I can agree it’s not so much important)
- The truth for this specific CPU question:
You won’t get any hard numbers. No situation with clients, Query is the same on each server.
It all depends how much activity you got on server.
You may have a server where only default groups exist and these 250 users are split in channel with max 2 users. So the load is not that high.
You may have the same 250 users in one channel and the load is much much more because talk status and every other data needs to be shared with these, which wasn’t the case before and so load becomes much higher.
Or these 250 users do switch a lot and get new assignments of groups. Which also causes load.
Or these 250 users do switch a lot but only some of these can see into other channels. Which reduces the load again.

For bandwidth you can calculate:
https://support.teamspeak.com/hc/en-us/articles/360002710657-How-much-bandwidth-does-TeamSpeak-require -
For RAM the 1GB for these 250 users should be enough.
-
For Hard disk 15MB may be enough, but when you plan that users can upload images and avatars, then you may need much more than this. 15MB is the bare minimum.

2 Cores may be enough, but we can’t ensure hard numbers as I wrote above.

So you are telling me that with a VPS with 2 vCore and 2 GB RAM I should stay safe in every possible case.
Or is better I take a VPS WITH 4 vCore and 4 GB RAM for a better safety?
2 Cores may be enough, but we can’t ensure hard numbers as I wrote above.

Its enough, we use 1 core at the moment 
(100-200 user and a ranksystem on our linux vps)
What about RAM?
cough cough

yeah yah 
I was referring to how much RAM did he choose, cause on some websites I read that every 50 concurrent users could require 1GB and I was suggested to choose a VPS with 4GB in my case
I read it in an unofficial teamspeak forum and then I started be confused a bit
OK? That’s a bit unrealistic (from our point of view).
There not as much data about a client stored in RAM to fill up this much with the amount of users.

Understood.
I don’t know how they told me that, they are not ts3 devs but as I understood they created a very very similar voip and told me to respect those requirements I wrote before if I want stay sure.
Btw is there a max RAM amount a single client can take?
200-300MB (in our case)
Hello everyone,
I’m planning to finally move my TeamSpeak server from a hosted provider to a self-hosted VPS, and I need your advice on a few key points. I’d really appreciate help with some clarity, as I want to avoid guessing and ensure everything runs smoothly without lag, crashes, or resource bottlenecks.
1. VPS Choice – Are These Good Enough for 256 / 512 Slots?
I’m considering hosting a TeamSpeak server on OVH VPS, and I’d like to know if the two configurations I’ve selected below are sufficient for maximum usage (full slot count, all users connected and active).
-
For 256 slots:
VPS Essential— 2 vCores, 4 GB RAM, 80 GB SSD NVMe (Intel) -
For 512 slots:
VPS Comfort— 4 vCores, 8 GB RAM, 80 GB SSD NVMe (Intel)
Do you think these two VPS models will perform reliably under full load?
Or would you recommend going higher or lower in specs?
2. Recommended Linux Distribution?
I can choose from the following Linux distros for the VPS:
- Ubuntu
- Debian
- Fedora
- AlmaLinux
- Rocky Linux
- CloudLinux
I’ve read that Debian may be a good choice because of its low resource usage and stability — do you agree, or would you recommend a different one for hosting TeamSpeak?
3. License Slot Flexibility – Any Way to Go Between 256 and 512?
Currently, my TeamSpeak is hosted by a provider.
I renewed it 6 months ago because I was unsure how to proceed with self-hosting. While the voice quality is good, there are too many limitations — I don’t have full control, can’t generate statistics, or customize the server freely.
That’s why I’m finally planning to move to self-hosting.
The only concern I have is about slot flexibility.
From the sales.teamspeak.com page, I can only choose between fixed license slot tiers:
32, 64, 128, 256, 512, 1024, etc.
In my case:
- 256 slots are perfect most of the year
- However, for 1–2 months per year, I might need something like 300 or 350 slots
With my current provider, I was allowed to temporarily increase the slot count during that period.
If I self-host, I assume TeamSpeak only allows fixed slot licenses — is there any way to upgrade temporarily or pay for a flexible number of slots, without jumping straight from 256 to 512 permanently?
I’ve seen the official documentation regarding server requirements, but it’s quite vague. I’m really looking for definitive, practical input from experienced admins or TeamSpeak staff to avoid future issues.
Thanks a lot in advance! 
With regard to the VPS specifications, please read this explanation and the accompanying breakdown:
Regarding the licenses you should reach out to [email protected]. They are much more knowledgeable in this situation and can help you choose the correct license.

Ok, so how can I know which VPS choose, if spend 100€/y or 200€/y or 300€/y or more?
Eventually I have access to YaTQA of the current one, there are some statistic, but I have no idea if can help to make this estimation.
The plan B would be to ask my provider resource consumption but its almost impossible they tell me.
The VPS provider depends on your preference and what they are offering for the price. That’s totally up to you. With the specs that they are providing on paper they should all be similar performance wise.

Yeah I know I can even buy a 1$/mo VPS but I’d like to avoid surprised, that’s why I listed server specs of two I choosen.
Any cheap server is enough (1 core , 1.5 Gigahertz, 512 MB of memory) for 400 users on the server, even communicating on 1 channel
