MATLAB: Is Matlab So Slow On My System

matlab execution duration is longer than previous

Matlab never used to be so slow on my system and I can not figure out why the processing speed is lagging.
I am running Windows 8.1.
The laptops processor is 2.0 GHz Intel Core i7, RAM = 16.0 GB OS is 64 bit
When running Nortons it states that Matlab is only using 1% of the CPU.
I cant understand why its lagging and any insight would be appreciated.

The profiler is the tool to find out, which commands take the time.
