基于多客户端结构的jTPCC测试系统的改进及实现

IMPROVEMENT AND IMPLEMENTATION OF JTPCC BENCHMARK SYSTEM BASED ON MULTI-CLIENT ARCHITECTURE

首先介绍了现在流行的数据库性能测试标准TPC-C;然后根据开源TPC-C测试软件jTPCC在使用过程中存在的问题对该软件进行了分析;由于存在的主要问题是客户端资源占用过多和服务器端压力不足,所以提出了将该软件从单客户端结构改进为可控制的多客户端结构的改进方案,并且实现了该方案。改造完成以后的测试数据表明,经过改进的软件比原软件测试数据更准确,使用更方便。

This paper introduces the popular database benchmark specification TPC-C, and the analysis of an open-source TPC benchmark software jTPCC against its problems on application. Main deficiencies are that excessive resources at clients＇ end are taken up and the pressure shortage on the server, so a reconstructed jTPCC scheme is presented, which improves the benchmark system from single-client architecture- based to muhi-client architecture-based. The test results derived from the implementation of the new scheme show, the improved software is more accurate and convenient than the original version.
