Speed of Azure File Service

Reading the documentation regarding Azure File Service I expected an easy and fast way to mount more space to my virtual Azure machine. However, after mounting a file service on my ubuntu machine (done exactly as explained on this page) I get super slow read/write speeds to this mount.

To give an example, downloading a 1000mb.bin file to my local disk:

sander@sanderpihost:~$ wget http://www.colocenter.nl/speedtest/1000mb.bin
--2015-06-28 08:34:38--  http://www.colocenter.nl/speedtest/1000mb.bin
Resolving www.colocenter.nl (www.colocenter.nl)... 5.39.184.5
Connecting to www.colocenter.nl (www.colocenter.nl)|5.39.184.5|:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: 1048576000 (1000M) [application/octet-stream]
Saving to: ‘1000mb.bin’

12% [==========>                                                                                ] 134,018,596 37.3MB/s  eta 25s  

And to my mounted folder:

sander@sanderpihost:~/myazuredisk/Incomplete$ wget http://www.colocenter.nl/speedtest/1000mb.bin
--2015-06-28 08:31:39--  http://www.colocenter.nl/speedtest/1000mb.bin

HTTP request sent, awaiting response... 200 OK
Length: 1048576000 (1000M) [application/octet-stream]
Saving to: ‘1000mb.bin.1’

 0% [                                                                                           ] 3,768,320    466KB/s  eta 34m 8s 

Is this expected? Is there any reason why this is soo slow? I would expect to hit much higher speeds than this meagre ±500KB/s I seem to get right now.

Network speed depends on instance size. A0 (extra small) instance with shared core (0.25) and 768MB of RAM has only 5Mbit/s bandwidth. Try to change instance size and test. In theory, Azure Files performance should be around 60MB/s (https://azure.microsoft.com/en-us/documentation/articles/storage-scalability-targets/) on standard storage.
