Test environment: CPU: duron700 (some projects have caused bottlenecks during testing, which may affect some test results) Memory: pc1_sdram 512 MB (JVM parameter is added with-xms256m-xmx256m to avoid testing project failure due to insufficient memory) Hard drive: IBM gxp 2 generation 30 GB 7200 RPM Windows2000 Professional SP4 Simplified Chinese version Database: oracle8.1.7 for WindowsNT JDBC driver: use the official driver ojdbc14.jar Hibernate closes the database connection pool: hibernate. Connection. pool_size 0 JDBC directly uses drivermanager to connect to the database If you do not use a connection pool, it is used to eliminate the deviation caused by the performance difference of the connection pool. If you do not use the app server, you can directly write a Java program for testing to avoid deviations from the app server. Persistent objects of the test: package com.fankai;public class Cat { private String id; private String name; private char sex; private float weight; public Cat() { } public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public char getSex() { return sex; } public void setSex(char sex) { this.sex = sex; } public float getWeight() { return weight; } public void setWeight(float weight) { this.weight = weight; }}For specific charts, see http://forum.javaeye.com/viewtopic.php?
