Hi!

GNAT 3.15p (WindowsXPProfessional / Linux'es)
--------
As I have understood there is a time-penalty when calling a protected
operation or task-entry. Im thinking about adminstrative cost
of the call, not loss of parallell'ism.

My situation is the following:
If I have a protected type that has two operation one "read" and one
"write". These are called by different tasks.
The "write" operation is called very seldom, but the "read" is called very
often.

Is there some approach to remove penalty from the "read" operation?


--------
Can someone point me to some literature or elaborate on this penalty?

Frank
