Improving the Performance of BlackBerry by Optimizing RAM Usage
The RAM memory capacity is one of the important factors that influences the performance of a smart phone. The right size and allocation of RAM is essential to boost the speed and response time.
Many users may not know the exact functioning of RAM. RAM is acronym for Random access Memory. It is the place where all the programs are stored temporarily while executing. They are copied from the more permanent hard disk storage as and when needed. It also has much higher access speed when compared to hard disks and hence is more expensive. Since the RAM has finite space, if the programs to be executed any time are more than the RAM capacity, they have to be constantly moved or swapped between the larger capacity hard disk and RAM.
For optimum performance of the computing system, efficient use of RAM is essential. The applications to be executed have to be scheduled in the most efficient manner. Powerful software called RAM boosters have been developed to address this issue.
MemoryUp is one such software developed by eMobiStudio Inc for mobile applications. It is a Java Virtual Machine (JVM) management tool that optimizes RAM usage for high end mobile phones. It has been specially customized for use with the BlackBerry Operating System. The RAM booster uses virtual machine concept wherein many virtual machines each with their own operating system reside on a host machine. The memory booster analyzes each J2ME program and dynamically allocates RAM to it in order deliver optimum performance. It controls all the JVMs running in the mobile system in order to achieve its objective.
Applications that are not running at any moment are rescheduled so that the resources can be made available to current application. This reduces frequent hard disk access, saves time and improves performance. For a person who uses email facility and also run office applications in a BlackBerry model simultaneously, the MemoryUp substantially increases response speed by optimizing the use of RAM by the various applications running in the front end as well as the back end.
Some of the technical characteristics of MemoryUp are given below.
* Supports boosting during start up, automatic boost as well as manual bost
* Calculating and displaying JVM RAM usage in real time
* Managing JVM
* Auto recovery of RAM to a pre set limit
* Easy to use interface even for a novice user
* Support in many languages like English, Italian, German and Spanish
* Optimizes memory usage by running in the background and recovering unused memory
* Specially customized for BlackBerry models
* Advanced features like preventing kernel from disk swapping, automatically allocate critical threads, using larger cache memory etc.
