DZone

This begins not only in designing the algorithm or coming out with efficient and robust architecture but right onto the choice of programming language. The legacy languages — be it ASM or C still rule in terms of performance. There were languages I briefly read about, including other performance comparisons on the internet.

HammerDB for Managers

HammerDB

Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. The TPC designed benchmarks for transaction processing (OLTP) and analytics (OLAP) and anyone can run these benchmarks, have them audited by the TPC and published on the official benchmark rankings. Derived Workloads.

Islands T-SQL Challenge

SQL Performance

L0 AS ( SELECT 1 AS c. I’ll assume you’re using an environment designed to support batch mode on row store either directly, e.g., using SQL Server 2019 Enterprise edition like mine, or indirectly, by creating a dummy columnstore index on the table. The CTE called C is based on a query that computes two row numbers.
