Transferring speeds are low

[vong]

Hi,

 

I finally got about hooking 2 computers up to the same network so I can transfer files to and from each pc through LAN but it's much slower than I had hoped. Transferring through LAN is around 25MB/s, compared to my Sandisk Extreme which is 120MB/s+ which makes it seem like I wasted time getting it all setup.

 

Were my expectations too high or is there something not right?

 

Setup is Modem/router > ethernet over power > switch > both computers

You're only as strong as the weakest link.  What drives are you transferring between?

25MB for EoP is pretty good. Because SoP may have a lot of noise depending on how many connections it has to go through the speed can vary quite a lot.

Both computers are using SSD's for the OS so those are what I'm using.

Yes, but if the information reads/writes to an HDD at any point that limits the transfer rate to the speed of the HDD.

I transfer straight from the SSD to the other SSD so shouldn't the speed be much higher?

So there are a couple of things to note.  Are you saying you are getting 25mb/s (megaBITS per second) or 25mB/s (megaBytes per second) as they are two completely different things.  At some point you care getting a bottleneck, whether it's your Ethernet or router.  Note the Mb to MB conversion is 8:1 so 8 megabits = 1 megabyte.  If I had to guess it would be your power over Ethernet that is the bottleneck. Double check max speed on that as if you are getting around 25MB/s transfer that's ~ 200mb/s speed which in actuality is most likely a 300mb/s Ethernet over Power adapter as it is very rare to get full perfect speed on those.

Oh, it's megabytes. The Eop is supposedly 500Mbps so I guess that's the reason huh.

Transferring at Gigabit the most you'll see is 125MB/s (max theoretical)

Did you plug the two computers together directly or use a switch? If the switch is only capable of 10/100mbps the most you'll see is 12.5MB/s or close to there.

I'm using a TP-Link TL-SG105 switch which says it can do 10/100/1000Mbps.

Or 120 MB/s in actual usage.

What kind of Ethernet cables are you using? If you want to get GbE speeds over longer distance (around 30 meters) you should use a Cat 6 cable.

I think it's Cat5e cable. I would've have used a long cable but it's unpractical seeing as the modem/router is in an office downstairs whilst the computers are upstairs.

Did you troubleshoot to see if using Ethernet over power is bottle-necking you? Gigabit Ethernet requires all 8 wires in an Ethernet cable I don't know if a power wire has the bandwidth to give the same results.

[Lehti]

Hmm... Then your issue isn't related to long cables. What does the Ethernet status window tell you?

Connecting both computers to the modem would be a real hassle since I'd have to carry both down stairs and bring monitors, keyboards and mice.

In Task Manger? Says the Link Speed is 1Gbps but I've never seen the Network Utilization gover over 0.50%.

If I've read everything correctly, it seems that it should be faster.

 

Are your powerline adapters plugged directly into the wall outlets(no surge protectors, 3 prong adapters, etc)?

Yep, directly into the wall outlets and yes they're 3 prong adapters.

I'm using Bitdefender on both computers and that gave me a bit of grief when trying to connect both to the homegroup, had to disable the firewalls to do it. Could that maybe be an issue?

Do you have something you can plug into the router to determine if you can get higher speeds from the router without powerline?  This will tell you if the problem starts at the router or is caused by the powerline.

[Windows7ge]

Is any ball of cable entwined in power wires? I've seen my transfer speeds tank from 110MB/s to 90MB/s just because my network cable was running parallel to some power wire.

Unfortunately not. Might just have to stick with the USB for big files then.

Not really, both cables run near power strips but I'd imagine that shouldn't affect the speed considering it's eop.

Does your router have a USB input? If so try tranferring between PC SSD and USB plugged into router.  Should get higher than 20 MB/s

I just tried to transfer a file but it says I need permission.
