The three numbers behind the load average:0.00,0.00,0.00 load average are 1-minute, 5-minute, 15-minute loads respectively.
The load average data is the number of active processes that are checked every 5 seconds and then calculated by a particular algorithm. If this number is divided by the number of logical CPUs, the result above 5 indicates that the system is overloaded.
Second line:
