Looking for High-Performance NVMe VPS With Dedicated CPU Cores

[Shrivelbitt]

I’m searching for a VPS provider offering true dedicated vCPU, not time-shared.
Minimum specs: 4 vCPU, 8 GB RAM, NVMe SSD, and a 1 Gbps port.
Needs KVM virtualization, custom ISO support, and stable uptime.
Prefer EU or US East locations. Is GTHost.com vps reliable? Other options please?
