I subscribe to a High-Speed Cable Broadband Internet service (25 MB download 3MB Upload). My Cable MODEM is a DOCSIS 3.0 Motorola SB6120.
The WAN port of my RVL200 Router having firmware v22.214.171.124 is connected to SB6120 MODEM.
From a PC connected to a RVL200 LAN port, when I test the speed of my internet connection using my service provider’s web tool or using 'speedtest.net', I get a solid 25-27 MB download and 3 MB upload. I've tested this over multiple days and times, always with the same results.
With this configuration as a starting point, if I enable logging of 'Allow Policies' under 'General Log' on the 'System Log' setup page, both my internet download and upload speeds dramatically drop to 2 MB. Disabling this feature restores the internet connection speed. It makes no difference whether I use a Syslog server or not.
It’s hard to believe that the RVL200 hardware so underpowered that it causes the WAN performance to be cut by 92% as it logs allow policies.
Is there a bug in the firmware that might be responsible for this? If this is normal behavior for this RVL200, an advisory should be shown in the routers setup help and manuals.
