Benchmarks

The below benchmarks were done with MySQL 5.4.12 on Mac OSX 10.5.8, testing against the database engine types for InnoDb and MyISAM. The ActiveRecord model names used were TestInnoDb and TestMyISAM. All times are displayed in seconds.

create in the below benchmarks refers to using ActiveRecord’s standard create method. import refers to using the import method added by activerecord-import.

Benchmarking InnoDb Tables

import(columns, values) without validations	0.081496	33.56x speedup
import(models) for 1000 records with validations	0.507533	5.39x speedup
