Create test table in MySQL and ultra-fast populate it with random strings. Usual INSERTS would take 100x times slower. This gist was prepared to benchmark LIKEs on inserted data. Further optimizations can be made based on this http://dev.mysql.com/doc/refman/5.0/en/insert-speed.html

	CREATE TABLE test (
	id INT NOT NULL AUTO_INCREMENT,
	last_name VARCHAR(255) NOT NULL,
	first_name VARCHAR(255) NOT NULL,
	PRIMARY KEY (id)
	);


	drop procedure prepare_data;
	delete from test where id>0;
