How do you measure latency performance?

A simple test to measure latency is to run a ping. This is a network diagnostic tool primarily used to test connectivity between two servers or devices. To ping a destination server, an Internet Control Message Protocol (ICMP) echo request packet is sent to that server.

How does latency affect performance?

Latency describes the amount of delay on a network or Internet connection. Low latency implies that there are no or almost no delays. High latency implies that there are many delays. One of the main aims of improving performance is to reduce latency.

How much latency is too much?

Generally, an acceptable latency (or ping) is anywhere around 40 – 60 milliseconds (ms) or lower, while a speed of over 100ms will usually mean a noticeable lag in gaming.

What happens when latency is high?

High latency decreases communication bandwidth, and can be temporary or permanent, depending on the source of the delays. Latency is measured in milliseconds, or during speed tests, it's referred to as a ping rate. The lower the ping rate the better the performance.
