Hi,
iv'e build my new freenas box, it' s a HP microserver G8 with 16GB ram and cpu GT1610.
In write, I've a normal performance, about 600 mbits, but in read I've about 20 mbits, so huge difference.
I've tried with CIFS and als owith ftp.
I installed from zero the 9.3 version, go with the wizard till the end, creating the dataset and the windows share in the wizard process.
Now I see I've the storage pool --> main dataset (unix lz4) --> various dataset shared from CIFS under the main dataset (windows lz4).
I tried dd and it report normal speed

If I read from CIFS or FTP the speed go to 2-3MB/s

Why the performance is very poor in read? 2-20MB/s is something wrong, I don't disk bottleneck.
Thanks to all.
