 # Performance
 
-:warning: The figures below are outdated. The performance of breakwater has increased significant in the meantime. I sadly don't have access to the server any more to run the benchmarks - happy about any figures for a beefy system. At GPN 21 we were able to reach 80 Gbit/s (40 via network and 40 via loopback) on a 20 core/40 thread system while serving > 500 connections :)

+See the [Server section](#server) below for up-to-date performance numbers.

 My Laptop has a `Intel(R) Core(TM) i7-8850H CPU @ 2.60GHz` (6 Cores/12 Threads) and 2 DDR4 RAM modules with 16 GB each and 2667 MT/s.
 The Pixelflut-server and Pixelflut-client [Sturmflut](https://github.com/TobleMiner/sturmflut) both run on my Laptop using 24 connections.
 These are the results of different Pixelflut servers:

 ## Server
-The server has two `Intel(R) Xeon(R) CPU E5-2660 v2 @ 2.20GHz` processors with 10 cores / 20 threads each.
-Another server was used as a Pixelflut-client [Sturmflut](https://github.com/TobleMiner/sturmflut).
-The servers were connected with two 40G and one 10G links, through which traffic was generated.

+As I don't have access to a dedicated server any more I did run the following benchmark on a Hetzner sever.
+
+Server type: [`CCX62`](https://www.hetzner.com/cloud) with `48` dedicated AMD EPYC cores and `192` GB RAM.
+[Sturmflut](https://github.com/TobleMiner/sturmflut) was used as a client using the loopback interface.
+The whole test setup did cost less than 1€ for one hour, so please feel free to submit performance numbers for other pixelflut servers or validate the results!
