I found this Minecraft host called ValueGameNode and it is all about high performance. They own their hardware and use strong AMD and Intel CPUs plus fast NVMe storage so big modpacks can run smooth.
Every plan gives full CPU access and they do not throttle. There are also unlimited player slots so you can invite as many friends as you want without paying extra for slots.
The prices are pretty cheap for what you get and plans start at 2.49 EUR per month. They have an easy panel that lets you install mods modpacks plugins and versions with one click.
They also have advanced backups where you can snapshot your progress and restore any world state really fast. On top of that they use enterprise DDoS protection so your server can stay online all the time.
They even offer a 2 day free trial and a discount code so you can test the performance before you decide to stay.
