压测小工具

最近给某东西压测(由于是私有协议没有通用工具可用),就自己写了个可以给压力的工具,可以支持QPS显示和响应时间的分布显示,有兴趣的可以拿来玩玩sql压测使用样例: ? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 import groovy.sql.Sql /** ``* @author <a href="mailto:wentong@taobao.com"></a> ``* @since 11-11-9 2:00 ``* ``*/ def client_num = ``100 private List<Sql> connent(``int num) { ``def result = [] ``1``.``upto``(num) {result.add(Sql.newInstance(``"jdbc:[mysql://127.0.0.1:3306/sbtest](3306/sbtest)"``, ``"test"``, ``"test"``, ``"com.mysql.jdbc.Driver"``))} ``return result } def clients = connent(client_num) def getId() { ``def total_record_num = ``80000000 ``def hot = ``20 ``def step = ``100 / hot ``BigDecimal hot_range = total_record_num / ``step ``if (RandomTest.nextInt(``100``) < ``95``) { ``return RandomTest.getId(hot_range, ``1``).intValue().toString() ``} ``else { ``return RandomTest.getId(total_record_num, ``1``).intValue().toString() ``} } def s = ``new StressTest() s.add({ ``Sql client = clients.``get``(it) ``client.execute(``"select id ,k,c,pad from sbtest where id =" + getId()) }, client_num) s.run() clients.``each {it.close()}
