Hi there!
we built a test Environment for Storage Spaces and Hyper-V with SMB 3.0. We have 8 SAS discs in a JBOD box. We connected two supermicro Servers. We get the expected Performance out of the discs until we activate continuous availability for Fileserver or scale out Fileserver. Before we activate it, we get a write peformance (just simple copying of large files) about 200-400 MB/sec. Once the continous availability is activated it drops to 38MB/sec.
Is this a "normal behavior"? Did we configure something wrong? Again, this is reporduceable. You can switch this option on or off which leads to an speed increase and decrease. I think the write cache is switched off in continuous availability, but is the impact really that high?
Thanks for any help!
