USB3 PCIe Cards with FreeBSD low speed

S

sol-invictus

Hello,

we wanted to connect a USB3 PCI Express card to our aging HP Proliant DL380 Gen8 (which has PCIe 3.0 slots with x16, x8 and a PCI-e 2.0 slot x4).

The USB3 cards are working but at a very low speed. When I test the speed by connecting a USB3 HDD the speed is about 5 to 7 MB/s with FreeBSD 13.3, 13.4, 14.0 and 14.1. With Debian 12 on the same Hardware I get rates from 110 to 130MB/s.

Hardware Specs HP Proliant DL380 Gen8: https://support.hpe.com/hpesc/publi...UID-E03B5B98-4537-4F81-8EE0-7F5A6517ADBD.html

There are different USB 3.x PCI-Express Cards in use.

Here is the output of

So I don`t know if it is the right thing to test the speed but this is how I tried:
Code: 
 [user]@[server][~]# mount -t ext2fs /dev/da2p1 /media/
[user]@[server][~]# dd if=/dev/urandom of=/media/test.img bs=4M count=1000 status=progress && sync
1000+0 records in
1000+0 records out

camcontrol devlist:
Code: 
<HP RAID 1(1+0) OK>                at scbus0 target 0 lun 0 (pass0,da0)

<WD Elements 25A3 1030>            at scbus6 target 0 lun 0 (da2,pass2)

So what I'm doing wrong here?

With Debian 12 the same hardware it is working fast and as it should, with FreeBSD (boot from USB Stick in Single Mode) I get the slow speed via USB3.
 
Could it be the ext2fs file system?

USB I/O very slow

Hi, I downloaded an 2,7 GB ISO image and copied to a pen drive formatted as ext2. The copying progress started with a write speed of 3 MB/s and went slower and slower and ended with a write speed of 627 KB/s. The copy process took me 47 minutes and I decided to test the write speed of Debian...
