DS718+ Speed is low when copying files to/from NAS #282

Closed Bkmz-GH closed 1 year ago

Bkmz-GH commented 1 year ago

Description of the problem

Hello! Card is connected to front USB port, not identified by the system when connected to rear ports. Card is identified by NAS as 2.5G, LEDs on card and unmanaged 2.5G capable switch are saying the same. Iperf3 tests from PC get expected results around 2.2-2.4G on send and receive. Card speed was also tested in direct connection between 2 PCs and with switch between them, both tests showing speed around 2.5G.

The strange thing is when it comes to copying files to/from NAS (SMB/FTP was tested) - speed is around 1G (~100Mb/s). When copying from NAS speed is always around 1G, but when uploading to NAS it starts at 2.5G but after some time (around 10 seconds) starts to decline ending at 1G.

Description of your products

NAS: DS718+ output of `uname -a: Linux bkmz-nas 4.4.180+ #42962 SMP Tue Oct 18 15:05:01 CST 2022 x86_64 GNU/Linux synology_apollolake_718+ DSM Version: DSM 7.1.1-42962 Update 2 NIC: Noname (10$ on Aliexpress) USB (Type A connector) 2.5G, identified by Windows as "RealTek PCIe 2.5 GBE family controller"

Description of your environment

  • connection using a Ethernet switch
  • PC: NIC model name - same as on NAS, also tried Intel I225-V
  • Ethernet switch: TP-LINK TL-SH1005
  • cable category: tried Cat.5e, then Cat.6

Bkmz-GH commented 1 year ago

Small info update: rear ports are working with active USB-hub but speed is also around 1GB/s. As far as I understand similar problems were encountered here and here. Attached screens for iperf3 results and PC to PC copying file through the same switch as NAS attached to. So the problem is almost definitely NAS/driver specific.

iperf3 pc2pc_copyfile

nagyrobi commented 1 year ago

Look at CPU usage of NAS during file copy. The USB driver relies on the CPU, thus having a CPU bottleneck will lower USB network speeds too.

Bkmz-GH commented 1 year ago

Hm, copying file takes more I/O waits.

Have you set the SMB version to SMB3?

IAMakarov commented 1 year ago

hello, image

bb-qq commented 1 year ago

Are you using SSD cache? It appears that disk access is the bottleneck, since iperf has no problems and the actual file transfer is fast for 10 seconds when uploading to the NAS. (I assume the first 10 seconds are being written to the cache in memory)

IAMakarov commented 1 year ago

You seem to be right. Don't how and when I'll be able to check with faster disks, but in case you are right your driver works on DS718+ with that noname card sold on aliexpress: image

Thanks for the great work!

bb-qq commented 1 year ago

Can we close this issue and re-open it if the symptoms do not resolve after verifying with a faster disk?

ok, sure
