Performance

We wrote a paper comparing JOPA with other object-triple mapping libraries (such as AliBaba, Empire, KOMMA, RDFBeans). It presents:

• A feature comparison of the libraries
• A benchmark showcasing typical application operations - create, retrieve, retrieve all (instances of a specific type), update, delete

More information about the benchmark, the methodology, raw data and the original results can be found at https://kbss.felk.cvut.cz/web/otm-benchmark.

However, the benchmark is quite old. The following table thus provides a perspective on how the performance of JOPA in the benchmark has evolved since version 0.10.7 (the version used in the original benchmark). The benchmark was run with the following setup:

• Linux Mint 21.3 (kernel 6.8.0-87-generic) - disabled network, no other applications running
• AMD Ryzen 7 PRO 4750U
• 32GB RAM
• GraphDB 10.8.4
