LibreQoS Test measures connection quality and latency while a network is under load.
About LibreQoS Test
LibreQoS Test measures internet connection quality with a focus on latency while the network is under load. It reports idle latency, average loaded latency, jitter, and packet loss, and shows expected performance for activities including browsing, gaming, streaming, backup, and calls. Results can be shared with a link or downloaded as PNG, JPG, PDF, or JSON. The test asks users to keep the tab in view until it finishes, because switching tabs can pause measurements and create gaps.
