hypervisor-steal-time-misread-as-cpu-utilization
When Hostinger VPS shows 60%+ CPU, check vmstat st (steal) column before assuming local workload — steal time 16-65% means the hypervisor is serving other tenants, not our code. KVM 8 is a shared-CPU plan; the top idle field reads ~3% while steal is 64%, making it look like near-total CPU consumption. File a Hostinger ticket citing steal time or migrate to a dedicated CPU plan.
