Upload speed dropping on Netgate SG5100 with FQ Codel enabled

Hi All,
I have a strange issue where my upload speed drops almost directly after I run a speedtest.
I am running the latest OPNsense version on a Netgate SG5100 with a Intel Atom C3558, 8GB ram and 128GB nvme SSD. Everything is running fine except this strange issue.
To prevent bufferbloat I also use SqM with FQ-Codel enabled which seems to work fine for download and upload but somehow the upload speed drops to around 650Mbit when enabled altough when I start the speedtest it starts @ 780Mbit which is the same speed the Download is capable of (Pipes are set @ 825Mbit).
I use a 1Gbit up/down PPPoE connection.
As far as I can see the hardware is capable because when running htop and check CPU I can see that none of the cores are reaches 100%...
Any ideas?
Edit: to clearify, when I disable the shaper I get a consistent 930/930mbit results, so somehow with shaper on for upload @ 825mbit it cuts the speed to 650Mbit instead of 780Mbit which is what happens for the download speed...
Another question I have is about Powerd. As far as I know this CPU doesn't have Intel Speedstep and in the bios not using any C-states.. should I enable Powerd or does it has no effect on this CPU?

Please follow this configuration guide:
https://docs.opnsense.org/manual/how-tos/shaper_bufferbloat.html
And if it still doesn't work, you really need to post screenshots of your settings.

Got the same behavior after configuring it on my new N100 build..
Just configured everything following this guide:
https://docs.opnsense.org/manual/how-tos/shaper_bufferbloat.html
Didn’t apply any tweaks or optimization.. but as soon as it is enabled @ 850/850 which is 85% of my 1Gb connection the download is holding nicely @ +-819mbit but upload drops to 750mbit after starting @ +-819mbit like the download speed…
Disabling shaper and both up and download reach 930mbit again…
Can’t remember this on older builds, could it be a bug??

Is ti possible you have set the "limit" other than the default?

Nope, didn't touch the limit to get a good baseline. Wanted to tune later on, but this strange behavior is holding me back..

Alright than try to disable ECN in the scheduler (Pipe)
https://docs.opnsense.org/manual/how-tos/shaper_bufferbloat.html#ecn
https://docs.opnsense.org/manual/how-tos/shaper_bufferbloat.html#create-pipe-for-download

I will try that!
I am using a PPPoE connection which requires a Vlan tag 6 for internet.
My MTU is set @ 1508 so the calculated PPP MTU is 1500.
