In fact, between 0.00 and 1.00 means there's no backup, and an arriving car will just go right on. 1.00 means the bridge is exactly at capacity. i have 1question.. Thanks.The top 10 monopolizing process would be better if sorted as a numberic key :
ps -eo pcpu,pid,user,args | sort -k 1 -r -n | head -10

So you're saying the ideal load is 1.00? For the numbers we've talked about (1.00 = fix it now, etc), you should be looking at the five or 15-minute averages. You may want to look at why your app it as 400%. Source By default, top displays this as a percentage of a single CPU.
