A load balancer is a system that distributes incoming network traffic across multiple servers instead of sending it all to one. It helps prevent any single server from becoming overloaded while keeping response times fast and consistent.
A load balancer sits in front of a group of servers and receives all incoming requests first. It uses a chosen method, such as round robin, least connections, or response time, to decide which server should handle each request. If one server goes down or becomes overloaded, the load balancer can route traffic away from it to healthy servers automatically. Large proxy networks use load balancers to spread requests across many proxy servers, keeping the whole system fast and reliable even under heavy demand.
Most proxy users only need to understand this well enough to debug it, not configure it directly.

Measure this metric without a proxy first, so you know what the gateway adds versus what was already there.
This concept governs the connection to the gateway and the gateway to the target -- check both when something looks wrong.
KnoxProxy manages this at the infrastructure layer, so most jobs only need to understand it well enough to debug.
A new ISP, VPN, or office network can change how this behaves -- confirm it again after any local network change.
A proxy provider uses a load balancer to spread thousands of customer requests evenly across its server farm instead of overwhelming a single machine.
Load balancers keep large proxy networks stable and fast, even when demand spikes or individual servers have issues. Without one, a single overloaded or failed server could slow down or break the whole service for many users at once.
Usually not directly. The load balancer works behind the scenes at the provider level, routing your requests to an available server in the proxy network without you needing to configure anything yourself.
Proxy networks handle requests from many customers at once, and a load balancer keeps that traffic spread evenly so no single server slows down or fails under too much demand.
