I am relatively computer code illiterate (I am a Mac guy and have no experience working within Linux), but have somewhat (easily) managed to build an Unraid server.  All seems to work well except my transfer speeds.

 

I am averaging 9.9 MB/s.  This average is over about 4.5 TB of movie transfers and many, many days.  I am tracking my file transfer with Net Monitor which shows a peak of 52.4 MB/s to as low as 16Kb/s leading to the average of 9.9MB/s.  Is there a reason that I can somehow get over 50MB/s through the pipe for tiny periods of time.

 

I am wired into my Apple Airport Extreme network.

 

I have tried using a cache disk, but achieved the exact same speeds as directly loading the files.  I have since disabled it.

 

I am wondering if there is something in the BIOS that I am missing.  I know nothing about the set up, but everything seemed to just work once I set my flash drive as the start up disk.  I did not change any other settings.

 

With 10 more TB of data to move, I'm wondering if I'll still be alive to actually use my shiny new server!

 

Thanks.

Post the outputs of "ifconfig" and "ethtool eth0". You can copy and paste from a telnet session in terminal.

dgaschk:

 

I ran if config but have no clue how to copy and paste.

Where did you run ifconfig? You on a Mac right? Open the terminal app in the utilities folder. Enter "telnet IP.address.of.server". Login to the server as root. Enter the commands. Using the mouse select the text in the terminal window then copy the text. Next, paste the text into a post.

I have a monitor directly connected to my unraid box.  I will log in via terminal and post shortly.  Thank you.

I'm afraid it's your Apple Airport Extreme. It meets it's wireless speed of 400Mb/s at a distance of five feet! Your speed (80Mb/s) is in the middle of what reviewers report

 

Try it wired if you can.

I am wired.  I switched to wired about 12 hours ago.  My wireless speed was even slower.

Is the client connected to the same Airport switch? Check the speed on the client.

What about your source machine?  How is that connected to the network?  Your speed is only going to be as fast as the slowest link.  9.9 is about what you'd get from a 100mbit network connection.  Caching from drive to OS on the source machine could explain occasional spikes above that, depending on how it's calculated.

 

BTW, you're only likely to average 30-35 on a full gigabit connection so it's still going to take a long time to transfer 10 gigs [meant tb] of data.

Thanks town/dgaschk

 

I am transferring the files from an externally mounted drive via usb on my desktop mac.  I'm assuming that it is the connected USB drive is 2.0 and that is the bottleneck.  Ugh.

Yep the USB drive could very well be. You might be better off plugging the USB drive directly into the unRAID machine and transfering it that way. Use SNAP or other methods available here.

Thank you.
