Solaris SPARC speed issue

Thank you again for all those answers. Sorry I was not able to reply sooner.
To answers your questions:
Regarding the compiler and optimizations, I am not sure what settings we were using during the 32 bit compile on Solaris 7. I would have to look for that info. I know it was using the native compiler and not GNU.
Regarding the 'native' code comment. My mistake, what I really meant to say is that it is mostly C code with very few calls into the C run time library or the OS. Very few dependencies on other code. Even the C++ is really minimal. The point is that what it spends time doing is mainly there in the code. The main thing we use that is not in the code are all the basic File I/O calls.
I am sure we can switch to dynamic C run time linkage, it was only done static because it has been done that way historically. This code was originally porting in 1992.
Thank you all again for your help. I feel fully informed and will talk to our customer about it all. We also plan to get a newer platform for porting.

I know that Sun make s a version of Solaris for Sparc platforms and also an x86 (Intel/AMD) release of Solaris. Can an application that runs on Solaris/Sparc also run on a PC running the x86 release of Solaris? Would a different release be required or any re-compling of the application?
