Question about using NAS for shadow play cache folder Open | Networking

I currently use my NAS to store my game clips, this includes the cache folder. I put the cache there because I don't want to put all the mileage on my rigs SSD.

My question is, if I'm constantly streaming my cache to my NAS, is this causing any appreciable network clogging or bottlenecking?

Game- Squad

LAN speed- 1000mbps

Resolution- 3440x1440

Fps- 70 locked

Shadowplay setting- default

In theory, yes. But I doubt any measurable difference could be seen outside of a lab environment.

I don't think it would be a bandwidth issue, I'm thinking queuing plays a bigger role here. But I have neither the knowledge nor the correct equipment to do anything about it.

What do you mean by queuing?

I think the current term people are using is bufferbloat.

"In general, the most effective way to combat bufferbloat is to implement so-called Smart Queue Management (SQM) in your router. Ideally, your router should be running the most effective SQM algorithms that specifically address bufferbloat"

Bufferbloat hapeens when you are sending/receiving data over the internet. It doesn't affect local network traffic.

That said, there is really no point in putting the cache on a NAS. You aren't going to wear out your SSD by using it as a Shadowplay cache.

If you want to be sure, play Squad for a few hours with and without Shadowplay enabled and look for any differences in network performance.

Is there any way to monitor this besides the good ol' eyeball dyno?

Not to my knowledge :(

Not unless your bitrate is set above your maximum network throughput, and I doubt ur recoding with a 1000 megabit bit rate.

Maybe best to look into QOS for your network that way u can designate priorities to different types of network traffic.
