Ive had my new broadband installed for a few days now, its BT infinity 80/20 fibre service. I built a pfSense box and have it configured in a fairly simple set up as my gateway and not doing much else. I have the BT provided VDSL modem between the pfsense box and the outside which i dont have access to.
I have been testing my speeds with a couple of 50GB newsgroup downloads. When I use the BT HomeHub router they supply, i get a fairly consistent 8.9MB/s download speed on any newsgroup download i try. When using pfsense in exactly the same configuration (ie just swapping the bt router for the pfsense box), my downloads are anything but consistent. I can sometimes hit 8.9MB/s for a couple of seconds or so, but usually the speed fluctuates between 3.8 - 6MB/s and I have my download client set to update the speed on 1 second intervals so i can see the massive changes in speed every second. I cant seem to get a consistent speed to max out the connection like i used to with my ADSL service or like I do with the BT supplied router.
This is my traffic graph over the space of about 5 minutes from the pfSense dashboard:
Can anyone help?!
