Yay! Another "I am using 10Gb and my speed is slow!" post.
NAS
OS: TrueNAS-SCALE-22.02-RC.1-2
Motherboard: Supermicro X10SRL-F
CPU: Intel(R) Xeon(R) CPU E5-1650 v3 @ 3.50GHz
NIC: Intel X550-T2
RAM: 128GiB
Storage: 1 main pool. 7 HDD drives in Z2.
10FT CAT8
No switch. Direct connect between NIC's.
Workstation
OS: Windows 11
Motherboard: ROG STRIX Z590-I GAMING WIFI
CPU: i9 - 11900K
NIC: Sonnet Solo 10G (Thunderbolt 3 adapter in Thunderbolt 4 port.)
RAM: 32GiB
Storage: Samsung 980, Samsung 960, 2x Samsung 850 in RAID0
Every transfer starts out 800-900MB/sec then within 5-10 seconds falls to 250-350MB/sec for the rest of the transfer.
CrystalDiskMark test always comes out about the same. But I do know this is misleading as it reports the fastest speed at any point of the test.
With limited knowledge in this field, I am at a loss as to why the speed drops off.
