Intermittent stalls, timeouts, choppy meetings, slow database synchronization, unstable cloud access or peak-hour failures can occur despite normal interface status and bandwidth charts. Causes include increased RTT, directional loss, jitter, micro-outages, routing changes, QoS policies, endpoint congestion or retry amplification.
Ping or a single iperf run is insufficient for long-term SLA reviews. BestPerf maintains active baselines for RTT, directional loss, jitter, micro-outages, TCP goodput and quality under load. Flow Hunter observes real sessions, retransmissions, handshakes, DNS/TLS/HTTP stages and event windows, supporting retrospective analysis and PCAP forensics.
