We are using HP aCC compiler on a HP Itanium box ( 11.23)
We are having some severe performance hits using exception
handling ( try/catch ) scenarios.
The online aCC documentation says:
HP aC++ exception handling has no significant performance impact at
compile-time or run-time.
We have not found this to be the case at all.
We are using the caliper measurement tool and it seems to indicate
that the application is spending 50% or more of it cpu cycles
in the unwind library.
We are not using any special arguments to aCC as exception handling
is enabled by default.
I can provide a simple short example to illustrate the case if needed
or requested.
Any comments, suggestions, ideas would be mucn appreciated.
Thank you,
Fred B.
