This paper provides an overview of performance issues related to mobile applications. As development of applications that run on mobile devices requires lot of resources and lead to wide area of performance issues. Among which the main categories are user interface design, application portability, quality, and security. Versatile program based application execution is generally intensely reliant on system and server application execution. The execution is typically slower thus and prompts a lessened client experience based on performance issues such as slow working, excessive memory and net usage, security problem etc. Also, a few applications may have higher execution than others as there is no standard. © 2016, International Journal of Pharmacy and Technology.
