What can i disable?

hello, i just switched back to turris today and noticed when i did a few speed tests , the ping was noticeably 5ms higher than when my previous (linksys e4200 vs) router was connected… i was getting around 8ms- ping to same server (google.com) over several pings on the linksys. now i have the turris omnia hooked up and im getting any where from 14ms-22ms this is with QOS turned on and off to the same server. is there maybe something i can disable thats causing slightly higher ping in the turris? any thoughts ?

i use latency sensitive applications and trying to get it as close as possible to that 8ms.

ps: nothing else is connected but computer to router at the time im checking the pings.
