So, please tell me the process how can I fix and improve the memory performance.

It depends on what you mean by the vague term "memory performance". I would suggest first using Shark to look at cache misses and/or DRAM bandwidth - that should help you to focus on any parts of your code where memory accesses may be a limiting factor.
