I have a gigabit network but have only been able to get up to 70MB/s sequential read from the server using CrystalDiskMark on my desktop. Copying a large file to the desktop SSD is worse, at less than 60MB/s. However, write speed with the CrystalDiskMark program gets up to 110MB/s, so I think the CPU, NIC, and other hardware are adequate.
Server specs:
AMD Phenom II X2 560 3.3GHz
Gigabyte GA-78LMT-S2P Motherboard
2x4GB DDR3
IBM M1015 IT-mode
Intel EXPI9301CTBLK NIC
RAIDZ2 8x 2TB Green
FreeNAS 8.2.0 RELEASE x64
dd benchmark on server:
Desktop specs:
Intel Core i7 2600K @ 4.5GHz OC
ASUS P8Z68-V Pro Motherboard
4x4GB DDR3
Intel EXPI9301CTBLK NIC
Crucial M4 128GB, WD 2TB Green
Windows 7 Professional x64
I have tried enabling autotune, but the only noticeable change is that it somehow decides that over 6GB of RAM should remain unused at all times... (versus about 1GB) and with this setting I can't even write multiple GB's of data (at no more than 20MB/s from a SD card) and stream a video from the server at the same time. Eventually it just becomes a lag-fest.
I have also noticed that (from the desktop) opening a folder with a few thousand pictures will take 10 seconds or more for it to list all the files. This didn't happen when I ran with FreeBSD itself instead of FreeNAS and has always happened since I started using FreeNAS.
Anyway, I'd like to improve the performance and any help will be appreciated!
