CenturyLink gigabit pppoe not achieving full 940Mb/s upload

[dpicray]

Hey all, I just switched from pfsense to opnsense and I'm having an issue where my upload speed on symmetrical fiber is at 750Mb/s. Not super sure how to troubleshoot so any advice is welcome!

Is there an option to test the upstream with multiple streams?

This was covered recently on reddit from a user also on CenturyLink:
