Is there an article somewhere that lists the common issues that affect windows with their fixes? I keep digging around each thread trying to find a good fix and there doesn't seem to a "Poor performance? Check this, and this and this" type thread / article anywhere. I think if there was a common list of things to check, it would cut down on all of us asking for help with poor performance, the product seems to be amazing, but performance just seems to be a re-occurring issue.

For Instance I've seen:

turning ODX OFF to fix performance
512b vs 4k cluster size
Using raid cache vs. starwind cache
L2 cache does nothing for read performance
Too much cache vs. too little cache
LSFS performance vs. flat file
Networking Jumbo frames?
Windows TCP Stack optimizations
Raid 64k Stripe size & 64k format does / does not matter?
Create drives initially small, let them sync, then expand them to avoid the initial sync length
Any type of tests to run to narrow down bottlenecks? I see poor performance with a single drive, single server using iscsi initiator locally.
RAID SSD Caching? Use or to not use?
It seems like the iSCSI initiator is the major source of problems, at least in my case, does starwind have another way to sync the data besides iSCSI?
