粗略看了activiti的sql的，在ativity engine包里边；
没什么头绪，先用excel记录数据量少的时候本机的性能情况；
不打印hibernate的sql；一刷一大片，还不输出参数是什么，这样的语句有什么意义哦，怀念mybatis；
<property name="showSql" value="false" />
让程序充分加载，取第三次的结果：
开始时间：2015-04-17 09:38:20.611
总记录数：57
结束时间：2015-04-17 09:38:22.788
总耗时：2177毫秒。
开始时间：2015-04-17 09:39:24.174
总记录数：57
结束时间：2015-04-17 09:39:26.110
总耗时：1936毫秒。
开始时间：2015-04-17 09:39:30.521
总记录数：57
结束时间：2015-04-17 09:39:32.331
总耗时：1810毫秒。
设置打印activiti中mybatis的sql；
<logger name="org.apache.ibatis.jdbc.ScriptRunner" level="DEBUG"/>
<!-- 目前本人只知道这句最有用 -->
<logger name="org.activiti.engine.impl.persistence.entity" level="DEBUG"/>
<!-- 下面是其他帖子抄的不知道有什么用 -->
<logger name="java.sql.Connection" level="DEBUG"/>
<logger name="java.sql.Statement" level="DEBUG"/>
<logger name="java.sql.PreparedStatement" level="DEBUG"/>
<logger name="java.sql.ResultSet" level="DEBUG"/>
配置logback；
slf4j包冲突的，在pom.xml里边指定slf4j的版本就可以；
数据语句：

爱死mybatis，要啥有啥；
这里感觉没分页啊；
找出涉及哪些表，然后手工拼接数据，成功插入了1条数据；
写程序插入数据；
NM，activiti新增条记录都n麻烦，能不能好好编程了；
换mysql存储过程，不错哦；

发现这activiti傻的，取出所有待办数据，然后在程序里边过滤数据，然后再做分页查询；
生成了1000数据，测试一把：
明显地分页优化完胜，问了下LTW优化的兄弟；回答是：因为原有的配置，就是不加LoadTimeWeaver的配置，会导致ORM的LazyLoad无效，等同于所有关联的实体都会被加载；
分页优化还要改很多代码，activiti缺乏灵活性真的有体会了；
不行咱就自己写SQL；
先试试代码上改吧；
/org/activiti/db/mapping/entity/HistoricProcessInstance.xml竟然没有关联act_hi_taskinst的地方；
什么鬼，这能算优秀框架吗？我加个.variableValueEquals("ASSIGNEE_", String.valueOf(userInfo.getId()))查询，出来这样的语句，select count(distinct RES.ID_) from ACT_HI_PROCINST RES inner join ACT_HI_VARINST A0 on RES.PROC_INST_ID_ = A0.PROC_INST_ID_ WHERE RES.END_TIME_ IS NULL and ( exists(select LINK.USER_ID_ from ACT_HI_IDENTITYLINK LINK where USER_ID_ = ? and LINK.PROC_INST_ID_ = RES.ID_) ) and A0.NAME_= ? and A0.VAR_TYPE_ = ? and A0.TEXT_ = ?，Parameters: 324(String), ASSIGNEE_(String), string(String), 324(String)，什么龟？
还得深入mapper.xml文件看看；
又纠结了，这怎么办？
