Network performance slowdown after a few hours
I have a ReadyNAS NVX connected to a Netgear GS108T smart switch through two CAT6 cables using link aggregation with LACP on the switch. The ReadyNAS ports are set up as 803.2ad LACP, with Layer 3+4 xmit hash policy. (The switch ports and LAG are set up as edge ports but either on or off doesn't seem to affect the problem).
Network settings from logs below.
Typically when I start the NAS up I can copy large files to my desktop at around 50-65 MB/s, which is quite reasonable considering the hardware limitations. However after a few hours of heavy file copying the speed goes down to 6-7 MB/s.
Rebooting the ReadyNAS speeds things right back up, so I can't help but think that something on the ReadyNAS degrades over time. Perhaps a full cache or something similar.
I'm looking for any possible solutions to this issue.

What firmware are you running? Also, what OS is the PC running?
FWIW, the bond will not increase your single-user speeds, so you could try disconnecting one of the cables and see if that makes any difference. My guess is that it won't though.
Yep, I tried single cable. No difference. I've tried connecting with only one switch between PC and ReadyNAS as well with the same results. Right now I'm running a Netgear GS108T smart switch for the NAS, connecting with two cables (LACP with RSTP) to a Netgear GS716T smart switch which connects to the PC.
Maybe it has something to do with the networking between the switches, but that wouldn't explain why restarting the ReadyNAS fixes it. Or?
ReadyNAS firmware is 4.2.2.28, and I'm on Windows 10. However I had similar problems in Windows 7 and 8.1, but they didn't appear as "reliably" as now.
Model: ReadyNAS NVX Business Edition [X-RAID2] Serial: 23N5047F00839 Firmware: RAIDiator 4.2.28 Memory: 1024 MB [6-6-6-24 DDR2]
I think you've ruled that out. If you want to be 100% certain you could try a direct connect. Maybe next time try rebooting the PC instead of the NAS, and see if it also recovers. How are you doing the copies?
