Hello, I have a CRS305-1G-4S+.
I want to put two 2 pcs on the same vlan/network but the transfer speed is low (capped at 100 Mbps) sometime a little higher.
The catch is if I put them on two separate vlans/networks it works fine. I disabled/enabled flow control, tried different MTU size to no avail.

I will try to reformulate my issue.
If i put 2 computers on VLAN10 (10.10.0.1/24) , the throughput/bandwidth is low but
if I put one computer on VLAN10 (10.10.0.1/25) and an another computer on VLAN 20 (10.10.0.129/25), the file transfer is at expected speed.
The CRS305-1G-4S+ is connected to pfsense via a DAC cable on sfp-sfpplus2. pfSense is the dhcp server.
One computer is connected to the CRS305 via S+RJ10 on sfp-sfpplus1.
One computer is connected to the CRS305 via S+RJ10 on sfp-sfpplus4.
Finally, I just want the 2 computers to communicate at full speed on the same VLAN/network.

First can you explain what your understanding of what the bold part below from the “working config” is supposed to do, give the other parts included below?
Also you will get more attention if you provide a diagram, and how the pfsense port connected to sfp-sfpplus2 is configured. See Step 1 from NEW USER POSTING FOR ASSISTANCE for some free tools to create diagrams. The whole article is worth a skim, as the easier you make it for people to help, the more likely you are to get help (and just documenting/explaining will often lead you to a better understanding of the problem). Here are some others worth skimming: Getting Answers - Increase your chances of getting an answer. And How to Report Bugs Effectively
