Slow write speed???


Lappen

Recommended Posts

Hi,

I'm wondering if my Unraid box is performing as it should. I have measured my speed when copying to my cache drive to 30 Mbps. This is a 1Gb wired Macbook Pro to my unraid box where cache drive is SSD.  Is it a fair transfer speed? Or could someone guide me in performing some other tests to see if my setup is in perfect condition.

Thanks for your replies.

 

I'm writing directly to the cache drive and not a share. I'll try to make some tests writing to different disks and shares with and without cache enabled...just to see the differences.

 

I'll try another source...but sourcedrive is also ssd.

I'm wondering if it could be the onboard NIC?

 

What's the prober way to measure transfer speeds?

I use a 2 year old MacBook Pro (and MacBook Air) for testing internet services.

I can consistently send and receive over 700Mbps of TCP from the built in (via Thunderbolt on the MBA) ethernet port.

Unless your Macbook is old, I doubt it's the Macbook NIC.

I'm really out of ideas...

To eliminate any switch or router, I connected my laptop directly to my Unraid box with a crossover cable.

Ran some speedtests and still getting 40 Mbps write to the cache drive and 450 Mbps read.

On the Unraid GUI I can see some network drops when receiving.

Could it be the onboard NIC on my motherboard thats faulty? Can I do some other tests to narrow down the problem.
