INSERT/UPDATE/DELETE тест

Jednonitni SQL benchmark koji meri protok INSERT, UPDATE i DELETE operacija na Firebird 2.5, 3.0 i 4.0. Rezultati uglavnom zavise od diska, CPU-a, RAM-a i veličine keša Firebird-a. Koristite ga kao brzu proveru hardvera - dobar hardver obično dospeva u gornjih 30% objavljenih rezultata.

Rezultati INSERT/UPDATE/DELETE testa na različitim diskovima, Firebird verzijama i računarima — Grafikon prikupljenih pokretanja. Kompletna tabela: insert_update_delete_results.xls.

Kako pokrenuti test

Kopirajte SQL skript ispod u datoteku, na primer c:\temp\dml-basic-benchmark.sql (Linux: /tmp/dml-basic-benchmark.sql).
Promenite putanju do baze podataka u prvom redu create database. Primer koristi Firebird 3 TCP (localhost:e:\inserttest4.fdb). Možete se prebaciti na XNET (xnet://Disk:\path\database.fdb) ili ugrađeni režim (disk:\path\database.fdb).
Zadržite isti firebird.conf koji koristite u produkciji. Da biste ga prvo podesili, koristite optimizovanu konfiguraciju.
Pokrenite isql (na nekim Linux paketima: isql-fb). Test kreira tabelu sa nekoliko indeksa, zatim izvršava 1 milion INSERT, UPDATE i DELETE operacija.
Baza podataka naraste na oko 3.6 GB - obrišite je nakon testa.
