DB Performance Testing

This tool can be used to benchmark various Database performance under "no-sql" usage conditions.

For the full explanation, check https://eadalabs.com/benchmarking-mysql-postgres-and-mongodb-performance-in-nosql-mode/

Database/Table Configuration

The database are used in "no-sql" mode, i.e. without any join between table. The objective of the test is to insert as fast a possible into the table, and read-back as fast as possible.

Two table configuration are defined:

• light table:

  • First column: index (int, primary key)
  • Second Column: integer
  • Third Column: integer

• large table:

  • First column: index (int, primary key)
  • Second Column: var char of 200 characters
  • Third to 10th Column: integer

Tests Scenarios

• Write

  • Insert to a table with 10 concurrent threads without transaction
  • Insert to a table with 10 concurrent insrrt thread using a transaction flushed every minute (only one thread for the transaction flush)
  • Insert to a table with 10 concurrent connections without transaction

• Read

  • Read the whole table data with one single thread
  • Read the table data with 2 theads: the first threads read the first half of the values, and the second thread reads the second half.
