Open Source is becoming more and more a “de facto” standard in the IT landscape of enterprises and large institutions. These enterprises and large institutions are actively looking for valuable solutions to replace traditional software vendors, which cause high TCO due to license policies and cause lock-ins that can be countered by proven Open Source alternatives.

IBM and Splendid Data carried out a benchmark to demonstrate that a completely (100%) Open Source stack can deliver an excellent price-performance ratio in all respects.

The Open Source stack is built on an IBM POWER8 server using PostgresPURE provided by Splendid Data, RedHat’s Enterprise Linux operating system and the PowerKVM hypervisor. Finally these results of the benchmark are compared to the performance of EnterpriseDB’s Postgres Plus Advance Server (commercial license, NOT Open Source) on a X86 Xeon Intel server (Benchmark reference: EDB Blog, Jason Davis, June 19, 2015).

Conclusions

  • The high scale factor results (meaning a large data set of 45 GB) show a 2 x better performance of PostgresPURE (based on PostgreSQL 9.4.4) running on PowerLinux S822L and compared to Postgres Plus Advanced Server running on an x86 Intel Xeon.
  • The high scale factor results, i.e.involving a large data set of 45 GB, show a 1.5 x better performance of PostgresPURE (based on PostgreSQL 9.5 Beta 1) at the Power Linux S822L server and compared to Postgres Plus Advanced Server on an x86 Intel Xeon platform.
  • The price per transaction on an IBM Power S822L server running PostgresPURE, based on PostgreSQL 9.4.4, is approximately 12 x less expensive as compared to an x86 Intel Xeon server running Postgres Plus Advanced Server.
  • The price per transaction on an IBM Power S822L server running PostgresPURE, based on PostgreSQL 9.5 Beta 1 version, is approximately 8 x cheaper as compared to an X86 Intel Xeon server running Postgres Plus Advanced Server. The combination of IBM’s POWER8 server in combination with Splendid Data’s PostgresPURE proved to be an excellent combination not only performance-wise but also cost-wise. This stack, combined with the ability to support enterprises and large institutions to migrate away from expensive alternatives like Intel servers running Oracle databases and other Oracle software components like Weblogic, provides a far less expensive and much better performing corporate database environment than provided by traditional vendors.
