The CPU is rarely used up to 100% because most code fails to utilize several cores efficiently.
OTOH a service loading the single core with the main thread is a frequent sight :( Interpreted languages like Python can easily spend 30% of time just on the deserialization overhead, converting the data from a DB into a result set, and then into ORM instances.
