[dba-Tech] ReFS on Windows Server 2012 R2 is screaming

Hi Gustav:

Impressive to say the least. I had never heard of the ReFS file system before and it seems like a definite improvement over the old NTFS.

Hi all



We're about setting up new file servers, Windows 2012 R2.

The new ReFS file system and the SMB 3.0 protocol is so fast that it can push the network speed over an Intel 1 Gb NIC above 100%. I've never seen this before and had to take a screenshot:

The drive is a Constellation server disk on a 6 Gb SATA controller in a Fujitsu Primergy T140 S1p Xeon based server.

If you use an SSD drive you may push the reading speed to 100% too.



If you use NTFS formatting, NIC usage is reduced to about 96%, but transfer speed is still beyond 100 MB/s.
