BoneCP 是一个高性能的开源java数据库连接池实现库。它的设计初衷就是为了提高数据库连接池的性能,根据某些测试数据发现,BoneCP是最快的连接池。BoneCP很小,只有四十几K(运行时需要slf4j和guava的支持,这二者加起来就不小了),而相比之下 C3P0 要六百多K。(BoneCP is a high-performance open source java database connection pool implementation library. It' s designed to improve the performance of the database connection pool, according to some test data found, BoneCP fastest connection pool. The BoneCP small four dozen K (run-time support for slf4j and guava, both of which add up to not less), contrast C3P0 over six hundred K.)
