Recently I upgraded my network from 50/3 Mbps to 300/20 Mbps (just to increase upload performance). The issue is, I can observe huge difference in speed.
I tried measurement directly connected to ISP modem, I can measure ~ 300/20 Mbps, but once I connect behind my Mikrotik, speed is around 200/20 Mbps (!!!).
Topology is:
ISP << coax >> Modem (bridge) << CAT 6a >> RB2011 << CAT 6a >> LAN (/WLAN)
Eth1 is main (to ISP modem), Eth2+ are in bridge.
OS: 6.42.3 (stable)
I run only few services on my Mikrotik, 4 firewall rules and one NAT (masquerade):
Code: Select all
[xxx@MT2011] /ip firewall filter> print
Flags: X - disabled, I - invalid, D - dynamic
0 ;;; SSH
chain=input action=drop protocol=tcp in-interface=ether1 dst-port=22 log=no log-prefix=""
1 ;;; HTTP
chain=input action=drop protocol=tcp in-interface=ether1 dst-port=80 log=no log-prefix=""
2 ;;; DNS (TCP)
chain=input action=drop protocol=tcp in-interface=ether1 dst-port=53 log=no log-prefix=""
3 ;;; DNS (UDP)
chain=input action=drop protocol=udp in-interface=ether1 dst-port=53 log=no log-prefix=""
/ip firewall nat> print
Flags: X - disabled, I - invalid, D - dynamic
0 chain=srcnat action=masquerade src-address=10.0.80.0/24 log=no log-prefix=""
Do you have any advice how to increase performance over the LAN?
Or do I have to upgrade to something better?
Over WLAN I can measure ~30/20 Mbps, which is slow but it's 2.4 GHz, so OK.
