parse time cpu	64	Total CPU time used for parsing (hard and soft) in 10s of milliseconds	3
parse time elapsed	64	Total elapsed time for parsing, in 10s of milliseconds. Subtract "parse time cpu" from the this statistic to determine the total waiting time for parse resources

开了个SR 问Metalink, Metalink 工程师说 这个是计算误差导致的，我要他们详细的官方文档，没得， TNND 忽悠哥哥
