CPU steal and noisy neighbours on cheap VPS plans

[Amanhasnoname]

Not all virtual servers deliver the same performance. Cheap shared plans often oversell CPU, and the effect shows up at the worst moments.

CPU steal is the time a virtual machine waits for physical CPU that's being used by others. On a quiet day it stays near zero. On a busy day, when many tenants are active, it can spike. A platform that's meant to process ticks instantly suddenly lags.

For scalping, the symptoms are subtle. Orders get sent a few hundred milliseconds late. Charts freeze for a second. An expert advisor falls behind during a news spike, exactly when fast processing mattered.

Checking is easy. Windows Task Manager doesn't show steal directly, but consistent unexplained lag with low reported CPU usage is a hint. Some providers publish dedicated resource plans that guarantee CPU.

For a few extra dollars per month, dedicated resources are cheap insurance against a bad fill.
