The ping rate is sometimes also called latency, and the terms are synonymous. Of these figures, the average ping rate (round-trip time) in milliseconds (ms) is probably the most useful to most people. In addition to raw ping rates (the minimum, maximum, and average round-trip times), it reports details such as errors, packet loss, and standard deviation from the mean. The Ping utility is available on almost all platforms and measures the round-trip time it takes for a packet of data to reach a server from your computer and then bounce back again to your computer. In common use, the term ping often refers directly to the ping rates themselves, so to avoid confusion we always capitalize the Ping utility and refer to ping rates in the lowercase in this article.

Properly speaking, Ping is a software utility which is used to measure ping rates.

This performance loss is often measured in terms of how the VPN impacts download and upload speeds, but there is also another factor in play: ping. After all, your data has to travel further as it gets routed via the VPN server, which also has to process the encryption and decryption needs of potentially hundreds of other VPN users. With some very rare exceptions, using a VPN will have a negative impact on your internet speed.
