I’m tinkering with the idea of creating some VLANs in my network, however after a simple activation of vlan-filtering on the bridge, my internet connection speed seems to drop by about 30% (as measured by speedtest.net).
My device is CRS326-24G-2S+RM, I’m using it as a router at the moment with all the ports under the same bridge interface.
How reliable is a speedtest.net test, or is there a better test I could perform? Is the performace drop to be expected? Why would activating vlan-filtering affect my WAN connection speed.
