SAP-SD benchmark and Unicode
Friday Dec 22, 2006
Some have asked me about the impact of SAP-SD benchmarks and Unicode.
Maybe I should explain first. SAP is moving to Unicode for all their software, meaning a single version will work in all geographies. The main difference is the use of double-byte characters so Asian and other languages can be supported. This will be phased in over the next couple of releases. The question if a Unicode or a Non-Unicode system is used in a benchmark has significant influence on the performance.
If I had to guess the performance difference will likely be dependent on the platform and may vary. But it may be from 10 to 30%? I also expect that systems running Unicode will needs 10-20% more CPU resources than a Non-Unicode system to achieve the same throughput and to run the same number of users.
