testcase

Connection conn = dataSource.getConnection();
  PreparedStatement stmt = conn.preparedStatement("select 1");
  ResultSet rs = stmt.executeQuery();
  while (rs.next()) {
  }
  rs.close();
  stmt.close();
  conn.close();

test config

property	value
initialSize	10
minPoolSize	10
maxPoolSize	50

测试各种并发场景下执行申请1,000,000（一百万）次总耗时的性能对比。

环境

OS linux 3.5.0-19-generic X86_64
CPU XEON E5-2450 双路共16核32物理线程
Memory 48G

这是一台双路至强CPU的工作站，比我之前在mac book pro上做的测试，更接近真实服务器的运行环境。
