Added back in basic benchmark support. To run:
ruby benchmark/benchmark.rb --adapter mysql --num 1000 ruby benchmark/benchmark.rb --adapter mysql --num 1000 --to-csv /tmp/results.csv ruby benchmark/benchmark.rb --adapter mysql --num 1000 --to-html /tmp/results.html

|

To run the benchmarks, from within the benchmarks run:
|
||||
ruby benchmark.rb [options]
|
||||
|
||||
The following options are supported:
|
||||
--adapter [String] The database adapter to use. IE: mysql, postgresql, oracle
|
||||
|
||||
--do-not-delete By default all records in the benchmark tables will be deleted at the end of the benchmark. This flag indicates not to delete the benchmark data.
|
||||
--num [Integer] The number of objects to benchmark. (Required!)
|
||||
--table-type [String] The table type to test. This can be used multiple times. By default it is all table types.
|
||||
--to-csv [String] Print results in a CSV file format
|
||||
--to-html [String] Print results in HTML format (String filename must be supplied)
|
||||
|
||||
See "ruby benchmark.rb -h" for the complete listing of options.
|
||||
|
||||
EXAMPLES
|
||||
--------
|
||||
To output to html format:
|
||||
ruby benchmark.rb --adapter=mysql --to-html=results.html
|
||||
|
||||
To output to csv format:
|
||||
ruby benchmark.rb --adapter=mysql --to-csv=results.csv
|
||||
|
||||
LIMITATIONS
|
||||
-----------
|
||||
Currently MySQL is the only supported adapter to benchmark.
