Hi,
I am experiencing strange dips in performance when transferring a 10GB sample file via SMB between the fileserver, which is a Windows Server 2019 Datacenter and the latest StarWind for HC Storage.
The dip always occurs at around 6GB has been transferred (so around 4GB left), dips do not seem to occure within the storage network with jumbo frames.
We also use one 1.5TB PCIe SSD as write-through SSD-cache as well as 4GB of RAM Cache.
Specs:
2x HP DL360 Gen9 Servers with 100TB in RAID6
HP Smart Array P840 SAS Controller
Edit: Storage:
RAID is 256 KiB (We have mixed file sizes - from Excel files to Cinema 4D and Creative Cloud of up to 50GB in size)
Windows Filesystem is ReFS and 64 KiB (again, for large I/O workloads)
StarWind Storage Block Size is 4096 Byte (chosen as recommended by StarWind Guidelines)
Is there anything I can take a look into for starters, maybe you have a suggestion.
Many thanks in advance--
