Ryan Marcus, dezvoltorul optimizatorului experimental Bao pentru PostgreSQL, care utilizeaz\u0103 \u00eenv\u0103\u021barea automat\u0103 pentru a optimiza execu\u021bia interog\u0103rilor, a publicat rezultatele test\u0103rii performan\u021bei optimizatorului de interog\u0103ri implicit al PostgreSQL. Testarea a acoperit versiunile PostgreSQL, \u00eencep\u00e2nd cu 8.4 (2009) \u0219i termin\u00e2nd cu 16 (2023). Performan\u021ba a fost m\u0103surat\u0103 folosind colec\u021bia JOB (join order benchmark), care include peste 100 de interog\u0103ri complexe cu un num\u0103r mare de opera\u021bii JOIN, viz\u00e2nd verificarea diverselor aspecte ale func\u021bion\u0103rii optimizatorului de interog\u0103ri.

\"Evaluation<\/center> <\/p>\n

Comparativ cu versiunea PostgreSQL 8.4, viteza de execu\u021bie a interog\u0103rilor de test \u00een PostgreSQL 16 a crescut aproape de dou\u0103 ori. Fiecare nou\u0103 versiune semnificativ\u0103 a PostgreSQL este, \u00een medie, cu 15% mai rapid\u0103 dec\u00e2t cea precedent\u0103 \u00een timpul testelor JOB.
