Using a Gigablast Cox connection with Adguard 1.5.14 for Mac turned on slows down the internet speedtest (https://www.speedtest.net) by one third of the speed. With it turned off it is triple the speed. What causes such a drastic reduction in speed and how can I increase the speed and still use AdGuard? With Adguard on I get about 160-250Mbs and with it turned off about 759Mbps.
