Hi,
I am developing a storport mini port driver for a SCSI HBA. The performance of driver is higher in Windows Server 2012 R2 DataCenter edition as compared to Windows Server 2016 14393 build. I am using the same machine, same tool (IO meter with same configuration) & same driver for various workloads from 512 to 4K to 1M RR/RW/SR/SW.
Do we have any know issues/limitations with storport driver in Windows Server 2016 ? What might be the reason. I debugged StorPortInitializePerfOpts and I am setting STOR_PERF_DPC_REDIRECTION, STOR_PERF_OPTIMIZE_FOR_COMPLETION_DURING_STARTIO & STOR_PERF_CONCURRENT_CHANNELS flags in PERF_CONFIGURATION_DATA
Thanks
