Sudden slow speeds on NAS
In the past few days I've noticed a dramatic slowdown in speeds when copying files to and from the 516. File transfers that used to take a minute or less now take 10 minutes or more. I've rebooted th...

Yep. It was that Netgear switch. I replaced it with a new 16 port switch and the ridiculously slow network speeds disappeared. It confused me that other network traffic seemed to work properly, but thsi solved the problem.
Thank you for the help.

System: Alert message failed to send.
I'm curious about this one - are you getting any alert email messages from the NAS? It's possible that email alerts aren't properly configured (though this could also be a side effect of the networking issues).

I iknow very little about bonding so I"m not sure what this problem is or if it may be the reason the NAS is transferring data so slowly.
It definitely sounds like a networking issue. What bonding mode is the system using? It'd be helpful to also know what switch/router you are using, and how the bonding is configured there.
I suggest downloading the log zip file and looking in network_settings.log. You'll find the ethernet stats there.
Rebooting both the NAS and the switch/router is probably the first step.
You can also try breaking the bond by disconnecting one of the two ethernet cables. Then retest the speed. After that, switch to the ethernet port and test it again. Since it could be a failing switch port in the router/switch, I also suggest trying a different port there.
NasTester is a convenient way to check the performance. http://www.808.dk/?code-csharp-nas-performance

StephenB, thank you for your reply. (I neglected to check the box when I posted this issue to “send emails when there is a response” so I just logged in to find yours.) Pardon for the delay.
First, I do get email alerts each night after the NAS runs its 5 or 6 Backup jobs. I also get them when the UPS goes onto battery power and again when it goes online.
Next, as I mentioned I know little about most of the Network options on the NAS. I have it configured with a static IP address. It’s currently set up with Teaming Mode: “Active Backup”. In the past few days as I’ve been trying to fix this I’ve tried “Transmit Load Balancing” and “Adaptive Load Balancing”, but neither one made much of a difference.
In my small network there is an older Netgear (dumb) 16 port switch so, as far as I know, I have no control over any sort of bonding going on there.
I downloaded the log file and examined the network_settings.log. As I recall, RX is for received and TX is for sent. The first section, LeafNets, lists no errors. Then bond0, eth0 and eth1 show lots of RX errors, in the 6- or 7-digit category, but with no TX errors.
I’ve disconnected both ethernet cables and tried using just one (new) ethernet cable plugged in to one of the ports. It didn’t seem to make much of a difference. I may be able to try a different switch if I can find it, also older Netgear. I don’t have much confidence that a different switch will help because all the other network traffic between the other few computers has not seen any slowdowns.
I tried that NAS performance download, but it’s an .exe file and all the computers here are Macs.
Again, thank you so much. If you have any other suggestions please let me know. If it could be a hardware issue I’d like to determine that and if Netgear can repair it I should look into it. I hope it doesn’t come to that.
