The curl command is not working correctly

You should set AES-GCM and enable UDP Fast I/O for better performance there.
However that isn't going to get you to the full rate there.
You are seeing ~15ms across the tunnel?
Did you bump the state table size?

Those images are too small to read I think.

@stephenw10 Im trying to send them as image instead of attachment but they are too large, do you mind if i send them with imgur?

Mmm, OK so no significant difference to throughput. I assume neither side shows any CPU cores at 100%?
I would try setting a lower MSS value and see if that makes any difference. If it does try to fins the actual tunnel MTU with some large pings.
Packet fragmentation across the tunnel can cause significant throttling. -
While downloading:
While uploading:
MSS -> 576 -> OpenVPN interface and bridge
MSS -> 1152
MSS -> 2304
MSS -> 4608
About the MTU i cant change on the interfaces because it says "This interface is a bridge member, its MTU is controlled by its parent bridge interface."

Hmm, Ok so it looks you are hitting a CPU limit on the upload with a single core at 100%.
Try MSS values at, say, 1400 and 1300. However with bridging in play normal fixes like that can fail since there's no routing....

MSS 1300 Downloading:
MSS 1300 Uploading:
MSS 1400 Downloading:
MSS 1400 Uploading:
While uploading some cores go to 100% but the speed is good but when downloading the cores dont go to 100% and the speed is low
-
Hmm, well I'd try a packet capture on the tunnel and see if the download is being fragmented or there are retransmissions etc.
