Java数据库连接池 BoneCP
BoneCP 是一个开源的快速的 JDBC 连接池。BoneCP很小,只有四十几K(运行时需要log4j和Google Collections的支持,这二者加起来就不小了),而相比之下 C3P0 要六百多K。另外个人觉得 BoneCP 有个缺点是,JDBC驱动的加载是在连接池之外的,这样在一些应用服务器的配置上就不够灵活。
当然,体积小并不是 BoneCP 优秀的原因,BoneCP 到底有什么突出的地方呢,请看看下面的性能测试报告:
Single Thread

Multi-Thread
- 500 threads each attempting 100 get/release connection
- No delay between getting/releasing connection.
- Pool size range: 50-200.
- Acquire increment: 5
- Helper threads: 5
Multi-Thread 10ms delay
- 500 threads each attempting 100 get/release connection
- We introduce a 10ms delay (Thread.sleep()) between the acquire connection and the release connection to simulate work being done with the connection.
- Pool size range: 50-200.
- Acquire increment: 5
- Helper threads: 5
Multi-Thread 25ms delay
- 500 threads each attempting 100 get/release connection
- We introduce a 25ms delay (Thread.sleep()) between the acquire connection and the release connection to simulate work being done with the connection.
- Pool size range: 50-200.
- Acquire increment: 5
- Helper threads: 5
Multi-Thread 50ms delay
- 500 threads each attempting 100 get/release connection
- We introduce a 50ms delay (Thread.sleep()) between the acquire connection and the release connection to simulate work being done with the connection.
- Pool size range: 50-200.
- Acquire increment: 5
- Helper threads: 5
Multi-Thread 75ms delay
- 500 threads each attempting 100 get/release connection
- We introduce a 75ms delay (Thread.sleep()) between the acquire connection and the release connection to simulate work being done with the connection.
- Pool size range: 50-200.
- Acquire increment: 5
- Helper threads: 5
Prepared Statement (single threaded)
- Fetches a single connection then calls 1,000,000 connection.prepareStatement(...) followed by an immediate statement close.

- Helper threads: 5
Prepared Statement (multi-threaded)
- 500 Threads each attempting 100 get/release connection with no delays. After obtaining a connection, make a call to connection.prepareStatement(...) followed by a close statement request.
