However, what is "MyModule::BEGIN"? Can I see more detail how to time
was spent?

Thanks.

The union of all BEGIN blocks encountered in package MyModule.

You can look at the options for dprofpp, like -S. And in probably -r, as
more than half the time in your program seems to be off the CPU.

There is also SmallProf, and some newer profiling modules I haven't looked
into yet myself.

But don't underestimate the usefulness of just looking at the code and
using your judgment about what parts are likely to be slow.

DProf is rather long in the tooth. The new hotness is Devel::NYTProf.
It has much nicer (and layered) reports that record at a much finer
granularity.
