Thanks for the additional details.
Many factors affect throughput when copying from a network location including:
- The size of files being copied (many small files tend to take longer than one large one).
- Congestion on the network from other connections.
- The speed of the data source drive, as well as whether any other disk activity is present here.
- Any slower network equipment between the USB3-E1000 and source system.
- What protocols are being used for the transfer.
Other factors may also be at play, but these are the most common ones.
To confirm if your USB3-E1000 is operating at full speed, it’s generally easiest to use a performance benchmark like iPerf to run some tests where the source isn’t data on a drive somewhere so you can avoid being limited by the factors above. When benchmarking the adapter, we connected one unit directly to another with a regular ethernet cable. A crossover cable isn’t required since the USB3-E1000 supports AutoMDIX or crossover cable detection. Since there’s no router in between, you’ll have to configure IP addresses manually for this test.
Softlayer has a great blog post on how to isolate what is slowing down network traffic: http://blog.softlayer.com/2011/using-…
Fundamentally, you’ll want to do a simple point-to-point test and then re-test as you add in each individual bit of network equipment in between the client and server. As you see speeds slow down after adding individual bits of equipment, you’ll know where your bottlenecks are if they are hardware. If you don’t see similar slowdowns just from adding network equipment, you’ll know the limiting factor isn’t hardware, but is something about either the data or the method of access.
Hope this helps, please let us know of any other questions!
