[SOLVED] Network transfer speed dropped drastically

[tankman1989]

All the sudden I'm getting about 5-10% of my standard transfer rate from my NAS. I used to get 40-50MB/s with 100MB bursts but now all the sudden I'm getting 2.8-3.5MB/s. Nothing has changed except I've freed up space on both the NAS and the target drive (RAID 0 SSD).

I get 100-350MB/s transfer to/from the SSD's when copying to/from other drives (local machine transfers). It also doesn't matter what drive I'm copying to from the NAS, as I get the same speed.

I have full duplex 1Gbit on the switch, both network cards and NAS are showing 1G.

Any idea where to look for issues?

Zyxel NSA320 & Netgear Prosafe 8 port gigait. NIC on PC is Intel Pro/1000 PT dual port adapter (current drivers).

Just found out that the NAS firmware was just updated a 6 weeks ago and it's only internally networked so it missed the update. I'll try that and see what happens. (the only fix is that it allows "Owncloud" to have it's own datapath, so IDK how that is going to help me..."

Strange thing is that it only started a week ago though.

Is the drive passing diagnostics?

The drive(s) are passing diagnostics and showing as healthy. I checked the admin panel and everything seems fine. I decided to reboot because there were some sessions/connections open that I wasn't sure were current and that fixed the issue.

For all the times I've asked clients if they've rebooted I should have thought of that but with a NAS (which usually stays on 24/7) I didn't think about that when all signs showed healthy.

Either way, after the reboot the transfer speed jumped to the highest I've ever seen yet, so this was a nice issue to solve. I guess it may be a good idea to either schedule timed reboots or at least have a way to drop any connection that hasn't been used in a certain amount of time.

I've found that if I get into a lot of activity, such as transferring images, vm's etc along with lots of downloads it can bring my network to a crawl. Both LAN as well as WAN. Sometimes a little quiet time restores everything. Other times I have to power cycle my modem, router, etc. Especially the modem.

Glad to hear!

Sometimes, nothing beats a good ole fashioned reboot.
