It is not that low. Correct me if I am wrong, netjack is TCP/IP, not AVB? transmiting at 20% of the maximum is subject to some care as the TCP/IP does not have clean priority management. Are you using the switch for other computers? do you send more data (especially when connect and siconnect)? is it a cheap switch (which run as "store and forward")?</div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: Cantarell; font-size: 14.666667px; font-style: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-tap-highlight-color: rgba(0, 0, 0, 0.4); -webkit-text-stroke-width: 0px; text-decoration: none;">If you are ready to sacrify a cable (or buy the sortest in the same serie), cut it and check if the pairs are separated by a metalic sheet to each other (+ the general rfi propection).
