which one is recommended: using static lib vs dynamic lib (shared object)

Question

I am working with an application in Linux. It supports both static and dynamic (.so) versions

From the performance standpoint, which version should a user use? The application performs computational tasks that require several hours of CPU time.

Any other advantage of using one lib over the other?

Thanks

Answer 1

From pure performance point of view:

Shared Objects are compiled as PIC (position independent code) that theoretically may be slightly less efficient then normal code on some architectures (including x86).

However, I don't think this would make any real difference.

From any other points

Use shared object, it has too many advantages over static library that it is just better alternative.
