Why my C# App use no more 25% of the total 4 CPUs' resources?

is there any setting options ?

Perhaps the application have only one thread? or perhaps locking
prevents more than one thread from running at a time.

because your app is single thread app and can use only 1 CPU (1/4 = 0.25)

It highly depends what your application is doing, if it only runs a single
active thread it will only use a single (and the same) CPU. Note that a quad
CPU box is more likely used as a server machine, that means that it will run
multi-threaded application services that will take advantage of the
available CPU's.

Very few apps are CPU bound and those that are should probably not be
written in .NET. For the most part .NET apps use threads to avoid blocking
on I/O therefore I would not expect to see multiple CPUs used.
