I've got a fresh reinstall of FZ Server 9.60b and my client download speeds seem to hit a limit at around 600KBps-1MBps per transfer. If more files are pulled by the same client, the new transfers hit the same speed limit, unless they hit the actual network bandwidth cap. I've got 20MBps up 300 down speeds from my ISP, so I should be seeing much higher per transfer speeds.
I've tried moving the files being pulled to SSD, NVME, and even a 3gb ramdrive, it dosent seem to matter what media they pull from, or how far away the clients are, 600KBps-1MBps per transfer is all they're able to do. I've made sure the speed limit setting for users and serverwide was disabled, tried disabling the firewalls, ports are forwarded properly, and all over plain FTP, no TLS, mode Z, or SFTP. Most of my settings are stock aside from bringing socket and internal transfer buffers up to 524,288.
I was able to saturate either my upload or drive bandwidth before I started messing with SFTP, when I saw the bandwitdh problem, I turned it off, but the problem persisted, even after a reinstall and cleanup.
Like I said, the speeds are per transfer, so if a user starts another download, it dosent slow down the speed of any exsisting transfers, unless the network or drives themselves cant keep up. Any ideas?

Re: Unusual server bandwidth problems
Which client software are you using?

Filezilla Client 3.30.0 and 3.45.1, Chrome, Windows terminal, and Firefox
Re: Unusual server bandwidth problems
Have you tried rebooting yet?
What's the latency between the client and the server machines?
How are the speeds if you connect using localhost using a client running on the server machine itself?

Re: Unusual server bandwidth problems
Yes, both client and server, this is an issue that I've been having for well over 6 months.
Latency between clients and the server average about 20-50ms, no wifi at any point in the link, direct connections only.
If I'm using localhost, I can get 100-110MBps.
