Over the past 8 months Dr. Bjarne Berg has been working on moving a very large SAP BW system to HANA.  Overall he and the team moved 15TB  of BW  data to a HANA environment and tested almost 100 of the most used queries.

They also did a comparison of  HANA vs. BWA and a HANA data load performance of over 500 jobs.

The tests were undertaken to see if it could actually be done and to get some performance benchmarks from testing a real system with real queries.

In his blog Berg looks at the real performance benchmarks which saw some spectacular performance in some areas . Some queries that took over 348 seconds on Oracle took 1.19 seconds on HANA (292 times faster).  About 10% of queries tested were at least 50 times faster on HANA.
