<< < (4/4)

From C>A+ all thanks to everyone on this post.

I have 1GB fiber with google Fiber for both upload and download.

Before
Bufferbloat Grade C
Unloaded 18ms
Download Active +17ms
Upload Active +171ms

Putting 900 Mbits/s on download pipe, and 850 Mbit/s on Upload pipe.
 
After
Bufferbloat Grade A+
Unloaded 18ms
Download Active +1ms
Upload Active +1ms

For some odd reason my upload active goes really high after 900, the sweet spot for me was 850. Hope this helps anyone.

Anybody here with AT&T fiber and using BGW320 ?
I set mine up as ip pass through, OPNsense baremetal latest version.
I am getting D grade all the time now. Before with spectrum non fiber on their gig service I managed to get A+ multiple times.

Update: got A+. Just had to dial in the upload cap
 

clutchmaster:
what am i doing wrong!

followed this exactly and discovered that i have no control over upload speed and has added a 300ms upload spike
either opnsense is bugged or this tutorial is wrong ive literally told it to cap upload to 5mbs and its still hitting max line capacity

or is it only capping upload when something is downloading

fixed it
