i have been almost a week with this firewall and i have had no trouble it.
not using the beta, but i dont think the firewall is causing your slow down…
I was having troubles with my speed and called my isp and then ran network test and stuff and it came to be that the cable line to my modem was not giving my modem enough power and that was making my speed slower, he put a 500 or a 900 mhz pad on the modem and it was a like a brand new thing everything is working faster. So check for spyware/trojan’s.network errors,call your isp if you contuine to have trouble is all i can say to you
