Hi all,
using direct attached fibre-channel disk we see throughput of approx. 500-800MB/s if we copy/paste a 28GB file to the same disk.
Once we install the Hyper-V Role, and re-test, we see a throughput of 126MB/s maximum performing the same task.
In addition throughput speeds become extremely varied ( from 126MB/s down to 1MB/s! ) for the same transfers.
Hardware and Software details given below.
Have you seen this behaviour? Can you recommend a resolution?
Best Regards, Sascha
