As we all know, physical memory gets fragmented over the period of time. With the smart phone era and the rich multimedia content, the problem seems to be more visible to the users. In the recent years there were many techniques and utilities developed that can either avoid or reduce the fragmentation or regain memory by killing the application and tuning some vm parameters. In this presentation I will showcase the techniques to quickly defragment entire system memory from user space without killing any application and bringing back the system memory to the initial state. I will also show how system responsiveness can be improved by using this techniques either from kernel space or user space. I will also present various experimental results of the defragmenter which was performed on Tizen based smart phones with 512MB RAM.
