20.7 Legacy Series / Huge network latency since upgrade to 20.7
« on: August 04, 2020, 08:21:05 am »
Hello,
one of my routers after upgrade to 20.7 on single (it has 4port network card, problem occurs only on 1 port) broadcom 1000Base-T interfaces has huge latency, it was ~0,5ms, right now it is ~20-25ms. I already changed "VLAN Hardware Filtering" to disable with some success but it was working on 20.1.9_1 like a charm, currently not.
On attached screenshot host monitored thru this interface on 20.1.9_1 and on 20.7 after ~22:00. Please help what else can I tune to drop this latency (hardware checksum offload disabled, hardware TCP segmentation offload disabled, hardware large receive offload disabled and VLAN Hardware Filtering also disabled).
Additional info: this bge1 interface is also used to vlan tags as the only interface in this router.
