NAS Transfer Slows PC

zom247 · 2 Aug 2017 at 20:06

The speeds from my NAS to my PC using ethernet are fine. However, what I have noticed recently is that when I am copying stuff over my PC lags and mouse movement becomes choppy, browsing with FF (latest) also becomes very slow. As soon as the transfer is finished it's all fine again.

Any ideas what's causing this?

What does Task Manager show? It might highlight what is being hit the most.

Do you have a crappy NIC? Have you tried updating the drivers?

Which AV do you use?

Copying to SSD or hard drive?

To answer all the questions:

Task Manager only shows 9% cpu usage (got a 1700X at stock with 16GB RAM).

Using the onboard NIC (Gigabyte Gaming 5) with the latest drivers.

Using Kaspersky and have done for ages, copying to SSD's.

It's only recently started happening. More investigating then.

What about other stats from task manager? Disk, network etc.

Disk went to 12% (SSD) and network transfer was 49.5 MB/s. All stats were really low. Going to try a direct connection from NAS to PC later to see what results I get from that.

Check even viewer for disk errors
Try disabling AV when doing it
Are you copying lots of small files or one large file?

Try latest network drivers from the NIC chipset manufacturer, not the motherboard manufacturer.

-edit, I see it's a Killer LAN, try removing the suite if you have that installed and just use the bare driver.

Just noticed, is the issue on WiFi?

Do you have more than one disk present? Do you notice the lag if you're copying to a secondary disk (i.e. not the OS disk).

Sounds like your disk might be bottlenecking, and any processes that need to read from disk are then experiencing a lag.

Had exactly the same problem yesterday. Running an i3 Intel NUC with a Synology NAS on the network. Use Kasperky 2017, updating the NUC networks drivers seems to have sorted this.

After a couple of weeks of being fine my PC has slowed down again whilst transferring from my NAS, I took a screenshot from task manager to see if that helps.

I'm copying files (large and small) from my NAS to PC over a wired ethernet connection (1 gig). The disks on my PC are all SSD (Samsung 850 Evo) and I have all the latest drivers installed for everything.

During the transfer my mouse freezes and browsing becomes really slow, once it's finished everything is fine. I never had this problem with my 2600k setup either, just since I've moved to Ryzen. In the grand scheme of things it's not a mega problem but it just annoys me and I like to find a solution to any problems I encounter.

Might be worth getting something more thorough like HWiNFO64 and monitoring that during said transfers. Has a tonne of information from every sensor in the system.
