Hi, all
I had a client program made by Delphi, it connects to Oracle and accesses data and makes a report. Now I'd like to re-write the program by Java. it has the same SQL statement and access the same DB.
But I found Java has low performance. in the same function.
Java call oracle.jdbc.driver.OracleDriver, and connect DB by driver manager. Delphi just spend 30 seconds. but Java program need 240 seconds....I don't know why Java performance is so bad.
Anyone can help me? Thanks a lot
