CIFS transfer at 10 Mbps

[Adith Sudhakar]

Version = 9.2.1.9

I'm trying to setup my NAS by moving all my content from my Win 8 laptop. I've connected them over LAN and my switch supports upto 100Mbps. For some weird reason I'm capped at 10Mbps! are there any args that I can set to improve this ? Or should I use something different to move my data off to the NAS box.

I've already taken a look at https://forums.freenas.org/index.php?threads/browsing-directories-slow.5338/page-6 since all performance issues related to CIFS seem to point to that thread. But the answers are redacted for some reason and this point, I don't know what else to debug..

It's likely that your laptop and server support gigabit ethernet. If so, upgrade to a gigabit switch.

The forum rules ask that you provide your hardware details. Give us the details on your server (including your NIC), make/model of your switch, and info on your laptop (especially the NIC it's using).

Who the hell keeps a 10/100 switch..... hell the cheapest decent one is 20 bucks!

Remember that the cables need to be at least CAT5E for gigabit speeds.

Also I wonder if you're at 10 MB/s or 10 Mb/s? because 10 MB/s is roughly 100 Mb/s so maybe you're not capped at 10 Mb/s.

That's what I was thinking too. One more reason to get a gigabit switch.

I have been following this post to attempt to fix my issues as well, could the OP replay as to if you fixed it and what you did. When I first set freeNas up for the first time and did my initial media transfer, I was getting around 115 MB +/- transfer speeds, at first I though it was slow. But then some googling had me realize it was pretty good. But now I am stuck at 11 MB transfer speeds, in both directions. I tried from an SSD, from various media, different times of day. I remeber this happened to me a few months ago, I performed a freeNas update/reset, and it was back to normal. No such luck this time. So I have been scouring the web and this post was the closest thing to my issue.
Just out of curiosity, if cables other than CAT5e were in the setup, say just CAT5 or CAT6, how much would they effect it? And if it matters, the cables are only about 10', freeNas box is next to main rig next to router. Router is Linksys EA6500.
A point in the right direction would be very helpful.
For future reference, should I have started a new post with this being the same issue? This post seemed dormant, sorry if I didn't follow protocol.

I googled up your router, it has x4 Gb ports, you don't have any other switched involved? Can you post your FreeNAS system specs please as well, and just for giggles your main rig specs. Make sure it's all gigabit.

Hello Darren, my spec are in my signature. Or so I thought i did that correctly, I'll copy and paste them to the actual post.

Very simple: CAT6 is better so no problem. CAT5 is only designed for 100 Mb/s so if you try to use it on a 1 Gb/s network, then the negociated speed can be 1 Gb/s (if you're lucky) and the real speed will probably be far worse than the 1 Gb/s limit, or the negociated speed can be 100 Mb/s and the real speed will be capped to that.

Ok, thanks Bidule0hm, so it's safe to say that even if I somehow switched cables to CAT5, which I highly doubt I ever would have being as the price difference is nothing, this is not my actual issue at the moment.

Can someone post a iperf for dummies "How To" , I keep getting an "connect failed" when I do iperf from an SSH from my main computer

Code:

  iperf -c 192.168.1.134 -t 60 -i 10 -f M  
connect failed: Connection refused

 

[Adith Sudhakar]

It was the router for me, I switched to a D-Link router that supports gigabit LAN, and now i don't have performance issues anymore.

Everyone *needs* gigabit .....

OK this will sound stupid but do you have an iperf server running?

Code:

iperf -s

on 192.168.1.134

No firewalls on .134?

By the way, CAT5e will work fine for gigabit, as will CAT6. CAT5 will work fine at 100 Mbps and it might work at gigabit (or it might not). Get CAT5e or better. The point is mostly moot as CAT5 is getting hard to find around here, CAT5e is available everywhere.
