Mike Matrigali updated DERBY-110: --------------------------------- Component: Performance Summary: hsqldb is faster than derby doing inserts (was: performance) Description: 1. create db name systable in derby and hsqldb (another open source dbms); 2. create table named a table ('CREATE TABLE aTable(id INTEGER NOT NULL, name VARCHAR(255) NOT NULL, description VARCHAR(255))'); 3. insert ten thousands row in table "atable" for(int i=1; i<10000; i++) { sql = "INSERT INTO aTable VALUES("+i+", 'haha', 'zhang'' test')"; stmt.execute(sql); System.out.println(i); } 4. derby spend 50390 millisecond; hsqldb spend 4250 millisecond; 5. conclusion: hsqldb has more perfect performance. Maybe derby need to improve it's performance. was: 1. create db name systable in derby and hsqldb (another open source dbms); 2. create table named a table ('CREATE TABLE aTable(id INTEGER NOT NULL, name VARCHAR(255) NOT NULL, description VARCHAR(255))'); 3. insert ten thousands row in table "atable" for(int i=1; i<10000; i++) { sql = "INSERT INTO aTable VALUES("+i+", 'haha', 'zhang'' test')"; stmt.execute(sql); System.out.println(i); } 4. derby spend 50390 millisecond; hsqldb spend 4250 millisecond; 5. conclusion: hsqldb has more perfect performance.
