Buffer Pool Extention - SQL 2014

Hello All,

I tried enabling buffer pool Extension feature on SQL 2014. To stress and compare an OLTP database results, we used Quest Benchmark factory tool.

Here is my environment details.

here is query that i used to enable BPE.

ALTER SERVER CONFIGURATION
SET BUFFER POOL EXTENSION ON
(
   FILENAME = 'd:\ExtensionFile.BPE',
   SIZE = 32 GB
)
GO

SQL VM is running on hyper-v host and SSD is configured as pass through device to the SQL VM.

With this experiment i didn't observe any performance improvement over the baseline results. am i missing anything here?

Any help would be greatly appreciated.
