Read/write slow on nvme drive - Supermicro X10DRL-CT

Title: Read/write slow on nvme drive - Supermicro X10DRL-CT

I have a Supermicro nmve supported hardware X10DRL-CT with a SSD sasa drive and an intel nvme pcie drive.. both drives are 2tb and I have used gpt with the latest 7.99 daily build from today

Using netbsd using dd if=/dev/device of=/dev/null bs=16k

Sata SSD : 33967620096 bytes transferred in 1899.583 sec(17881619 bytes/sec)

pcie SSD : 308527169536 bytes transferred in 2384.793 sec(129372725 bytes/sec)

Using ubuntu live boot disk with diskutility I get

Sata SSD :  504MB/sec

pcie SSD : 3100MB/sec

So im wondering if theres any tweak/config  on netbsd that is needed to get higher speed on the pcie .. copying a 200mb files take a minute on the sata drive while it takes 6 minutes on the pcie.. so its 5 times slow rather than being faster
