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

• 1,000,000 get connection / release connection requests
• No delay between getting/releasing connection.
• Pool size range: 20-50.
• Acquire increment: 5
• Helper threads: 1
• Partition count: 1

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.
