TFS ubuntu performance

[Azerty]

I have a problem with my VPS where the server takes 15 minutes to open and when it opens the lag is constant.
VPS:

CPU Amd ou Intel Turbo
5vCore @ 2,7 GHz until 5,1 GHz
RAM 16GB DDR4
Disc 100GB NvMe

Is there any configuration to be done so that the vps runs more powerfully on Ubuntu 22.04 LTS? I analyzed the performance and it does not exceed 20% vcpu

I never heard about any linux configuration related to slow OTS loading. All problems are often related to low quality VPS (ex. 16 real cores of CPU sold as 512 'vCores' to VPS buyers, so your "5vCore" can be 5/32 of 1 single CPU 2.7GHz core = 0.79 GHz single core CPU, like in 2001!).
Benchmark your VPS:

Benchmark your VPS (or dedicated server) CPU, RAM, network and HDD/SSD

There are many tutorials in Google 'how to benchmark XXX'. In this thread are tools I tested on Ubuntu 20.04. With all these tests, it should be easy to compare VPSes and Cloud offers from different companies. 1. CPU 1.1 CPU - 7zip compress/decompress Install: sudo apt install p7zip-full...

There can be multiple problems: slow disk, slow RAM, overloaded CPU (by other VPSes hosted on same physical machine).

You can compare your score to other VPSes/Clouds/dedicated servers I've tested:

EDIT:
OTSes often spent 90% of startup time on loading RL map .otbm file, which uses few GB of RAM and requires a lot of CPU/RAM operations.
If you are running canary/otservbr server (or some modified version of it), some versions had pretty much to calculate on startup - not related to loading of .otbm. It generated a lot of CPU usage, up to 2 minutes even on fast CPUs. It's fixed on newest versions of canary, but if you run some old version, you can get into this problem.
