Is it always guaranteed that a multi-threaded application would run faster than a single threaded application?

I have two threads that populates data from a data source but different entities (eg: database, from two different tables), seems like single threaded version of the application is running faster than the version with two threads.

Why would the reason be? when i look at the performance monitor, both cpu s are very spikey ? is this due to context switching?

what are the best practices to jack the CPU and fully utilize it?

I hope this is not ambiguous.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
