TS-873A - Slow download speed

[Deepcuts]

Hello,

Long time Synology user and decided to change teams to see if the grass is greener on the other side, so I purchased a TS-873A https://www.qnap.com/en/product/ts-873a

Test setup
QNAP TS-873 with 64 GB (2x32) of ECC RAM @ 2400 Mhz, 8 Seagate Exos X18 18 TB and 2 Corsair MP600 Pro XT nvme 2 TB SSDs (for caching)
Of course, one of the Seagate HDDs was DoA, as it usually happens with Seagate and after one moth of waiting for the RMA, I stared to build my new toy.
Workstation used is an AMD 5950X, with 64 GB RAM, Aquantia AQC107 10 Gbps nic and 1 Corsair MP600 Pro XT 2 TB SSD (~ 7+ GB/s read and write)
Switch is a Mikrotik CRS312-4C+8XG
Tested with RAID5 and RAID50 with 8 HDD, no caching, because...QNAP does not support my SSDs. Seems QNAP cannot read a serial number entirely and throwing WWN errors. Both SSDs work just fine together under Windows or Linux.
QNAP's response: buy another brand. Not a good start.
For SSD benchmark I used two HP 920 nvme SSDs, 256 GB each in RAID0.
All volumes on the NAS are empty.

Problem

Download speed from NAS to workstation is not what I expected for this setup, maxing out at 400 MB/s while using SMB, no matter the RAID type or if HDD or SSD.

Everything looks good on the network side, fully saturating the 10 Gbps link

2. RAID5 benchmark 8xHDD

Both RAID5 and RAID50 behaved almost the same, showing the volume can sustain higher than 400 MB/s reads.

I guess the question is: is this the performance I should expect from TS-873A?
Anyone managed to find a way around this speed limit?

Thank you.

Was about to say .. 400MB\s would be in line with the extremely low NVME speeds shown up there (566MB\s sequential read).

Your setup should max out 10GbE for sure (just from the plain disk .. no cache)

[Toxic17]

is your MTU set to max on the NAS and any Switches?

also lets test the disks themselves.

SSH to your NAS run the following:

Code: Select all

qcli_storage -T force=1

Code: Select all

qcli_storage -t force=1

Found the culprit

Short story
Like Kaspersky, it seems Norton also greatly affects network speeds, even when all AV/Firewall, etc components are DISABLED.
Uninstalled Norton Antivirus and the speed is now symmetrical 1+ GB/s

Long story
Booted an Ubuntu Live USB. For some reason, the latest Ubuntu Desktop cannot write to NTFS partitions even with the correct mount options, thus, I could not benchmark.
But, I opened the web portal for my NAS and using the File Station I tried downloading a 7 GB file. Speed was around 650 MB/s on https, so I knew something is wrong with my Windows install.
Back to Windows, I rebooted into safe mode with networking and again, the download speed was 1+ GB/s.
At this point I was about to reinstall Windows, but 1st, I tried uninstalling Norton Antivirus. After a reboot I was please to see full 1+ GB/s download speed.
Like Kaspersky, it seems Norton also greatly affects network speeds, even when all AV/Firewall, etc components are DISABLED.

@Toxic17
Thank you for the reply.
In my experience, MTU never does anything for 10 Gb/s, so I keep all my network at 1500.
