Hi All,
Thanks for all your hard work on this. I've noticed something a little bit odd with read/write speeds. Just wondering if anyone has seen anything similar?
Just to confirm all network speeds are solid, all over CAT6/6a and IPerf to and from server is consistent 1Gb both ways. I am using 5x 1Gb files in a single folder for all tests. Ill list below what I am seeing:
PC transfer to SMB share on Cache = Transfers at full speed (112Mb)
PC read from SMB share from Array/Cache = Transfer at full speed (112Mb)
PC write to iSCSI on block volume on dedicated SSD = Transfer at full speed. (112Mb)
PC read from iSCI on block volume on dedicated SSD = Transfer at full speed (112Mb)
PC write to iSCSI fileIO Blockstore volume on Cache Drives = Transfer at a flat 17Mb
PC read from iSCSI fileIO Blockstore volume on Cache Drives = Transfer at a flat 20Mb
I have moved the Blockstore from the Cache drives to some spinning disks in the array and its the same result. I did expect some overheads/loss in terms of throughput put not 95Mb(ish). Run similar tests using TrueNAS as a VM and it was perfect, wire speed all the way.
Any pointers would be welcome.
Thanks,
