页面加载奇慢，打开TRACE后发现
运行时间 : 39.8479s ( Load:0.0057s Init:39.7117s Exec:0.0667s Template:0.0637s )

其中流程部分的内容如下：
[ app_begin ] --START--
Run ReadHtmlCache Behavior [ RunTime:0.000826s ]
[ app_begin ] --END-- [ RunTime:0.000918s ]
[ view_template ] --START--
Run LocationTemplate Behavior [ RunTime:-39.765297s ]
[ view_template ] --END-- [ RunTime:0.000889s ]
[ view_parse ] --START--
Run ParseTemplate Behavior [ RunTime:-39.766245s ]
[ view_parse ] --END-- [ RunTime:0.057557s ]
[ view_filter ] --START--
Run ContentReplace Behavior [ RunTime:-39.823868s ]
Run TokenBuild Behavior [ RunTime:-39.824489s ]
Run WriteHtmlCache Behavior [ RunTime:-39.825095s ]
Run ShowRuntime Behavior [ RunTime:-39.825431s ]
[ view_filter ] --END-- [ RunTime:0.002160s ]
[ view_end ] --START--

为什么Run ParseTemplate Behavior的时间会是-39.765297s 呢，好奇怪。
