What is ideal load average in Linux?

Optimal Load average equals your number of CPU Cores. if you have 8 CPU Cores (can be found using cat /proc/cpuinfo) on a Linux server, the ideal Load average should be around 8 (+/- 1).

Why the load factor is always less than 1?

The value of the load factor is always less than 1 because the value of average load is always smaller than the maximum demand. If the load factor is high (above 0.50), it shows that the power usage is relatively constant; if it is low, it means a high demand is set.

How is peak load calculated?

To calculate your load factor take the total electricity (KWh) used in the month and divide it by the peak demand (power)(KW), then divide by the number of days in the billing cycle, then divide by 24 hours in a day. The result is a ratio between zero and one.

How can I increase my load factor?

Reduce demand by distributing your loads over different time periods. Keeping the demand stable and increasing your consumption is often a cost-effective way to increase production while maximizing the use of your power. *In both cases, the load factor will improve and therefore reduce your average unit cost per kWh.

What is a good load factor?

It is the ratio of actual kilowatt-hours used in a given period, divided by the total possible kilowatt -hours that could have been used in the same period, at the peak kW level established by the customer during the billing period. A high load factor is “a good thing,” and a low load factor is a “bad thing.”
