Determining if nonshared libraries help performance
One method of determining whether your application is sensitive to the shared-library approach is to recompile your executable program using the nonshared option.
If the performance is significantly better, you may want to consider trading off the other advantages of shared libraries for the performance gain. Be sure to measure performance in an authentic environment, however. A program that had been bound nonshared might run faster as a single instance in a lightly loaded machine. That same program, when used by a number of users simultaneously, might increase real memory usage enough to slow down the whole workload.
