Read speeds are half of write speed
Posted: 19 Dec 2015 19:08
This is my first time using nas4free, so bear with me. I have an old Intel socket M mini-itx motherboard with a Core 2 Duo T7200 and 3GB DDR2 RAM. It has two 4TB Toshiba hard drives connected to the onboard ICH7 interface. It also has dual on-board Intel Pro/1000 NICs. I configured the drives in software RAID 0 and formatted it UFS to use for storing backups. I don't need any of the ZFS features for that.
I setup a SMB3 share and tested performance by copying a 3GB Windows 7 ISO file to and from it. Write speeds consistently peg the gigabit eithernet, but reading the file back will never go faster than about 70MB/sec, and typically settles around 60MB/sec. I've tried setting the send/receive buffers to 0 as suggested in some other threads but that didn't seem to change anything. How can I get better read speeds? This is important because I have over 3TB worth of data that must be backed up and later restored to a new server. Once the new server is operational the nas4free box will only be used for storing backups and later on replication offsite.
