Latency refers to the amount of time it takes for data to travel from your device to a destination and back, measured in milliseconds. For general browsing and streaming, anything under 100 ms is fine, while for intense gaming, youll want to shoot for 50 ms or lower. Generally, when you test your ping, an acceptable number is anywhere around 40 to 60 milliseconds (ms) or lower, while a speed of over 100 ms will usually mean a noticeable lag in gaming. Anything at 100ms or less is considered acceptable for gaming, but 20-40ms is optimal. Ultimately, the lower the latency, the better the experience, especially in fast-paced games where timing is critical.
