Slow uploads from Max to Flashstor NAS

[phrehdd]

As the titles says - my uploads from my Studio Max to the Flashstor 6 is very* slow.

I was uploading fair sized media files via FileZilla FTP and at best got around 23 mbs.
Interestingly enough, I uploaded afterwords two similar sized files at the same time and they each did 23.1 mbs.

Any thoughts of where the bottleneck is ?

Thanks

some more details would probably helpful - switch/router model, macOS version, wiring, etc.. We are talking transfers in your local LAN here (?), so for starters I would suggest looking into using SMB:// or WebDAV instead of ftp:// - is there a specific reason for that? Also: why FileZilla?

Studio Max M4 wifi to Asus BQ16 (WiFi 7) using MLO. Flashstor at about 50 percent capacity and connected via LAN cat 6, Flashstor has both AFP and SMB active.

Mac <----wifi 6e------>ROUTER<----cable---->NAS (4tbx6 NVME RAID 5)

Speed tests for Mac and for NAS 1000+ dl Mac and 750+ ul for NAS (based on speed tests apps on each)

Means of uploading to NAS - FileZilla FTP client (non Pro). Files all larger media files 18 gigs plus.

Let me know if I can provide any other useful data. Today, I did uploading today and it went up to about 41mbs. Very odd. Thanks for your time.

Can you try using a different connection method? SMB, SSH, SFTP/FTPS, AFP even?

I am not familiar with the brand of NAS, but if it is just a linux box under the hood and you can install command-line tools, you could always install iperf and run tests between your mac and the NAS. This will give you a good idea of the maximum speed between two networked devices, excluding specific protocols and storage limitations.

It could just be that that's the speed of your NAS of course. If you have another device which can connect to your NAS you should test to see if it is a problem specific to your Mac.

SMB and AFP along with FTP,FTPS are standard .. SFTP would requite another setup to work properly.
I did change the cable from router to NAS...not really a difference between them. The Mac and the router I believe are both set at 1500 MTU. I would imagine the NAS is the same.
