2个服务器的top：
从cpu，内存，io，线程数上的运行情况分析，2个服务器运行状况都差不多，但是为什么load average 就差这么多呢？ 谢谢
第一个服务器，负载很低：
4:12pm up 871 days, 6:53, 13 users, load average: 0.86, 0.90, 0.74
794 processes: 793 sleeping, 1 running, 0 zombie, 0 stopped
CPU0 states: 7.5% user, 1.0% system, 6.3% nice, 91.3% idle
CPU1 states: 5.1% user, 20.0% system, 4.2% nice, 74.2% idle
Mem: 1030524K av, 993712K used, 36812K free, 0K shrd, 9168K buff

差别这么这么大呢？希望达人们帮忙分析分析，我实在找不出原因，谢谢。
