Compcache FOR LINUX

Compcache is a valuable tool designed to enhance the performance of Linux systems by creating a RAM based block device called ramzswap, which serves as a compressed swap disk. By compressing pages and storing them in memory, Compcache effectively increases the capacity of the RAM, allowing more applications to run smoothly within the given memory constraints.

Key Features:

• Enhances system performance by creating a RAM based block device


• Compresses pages swapped to disk and stores them in memory


• Increases the capacity of RAM virtually


• Optimizes memory usage for a variety of use cases

Technical Specifications:

• Creates ramzswap.ko kernel driver


• Generates rzscontrol.rzscontrol userspace tool


• Supports initialization and configuration of individual ramzswap devices


• Allows seamless loading and unloading of Compcache modules

Installation and Usage:

To make the most of Compcache, follow these simple steps:

1. Load Modules: Use modprobe to load dependency modules and insmod to load the ramzswap module with desired parameters.


2. Initialize: Configure and initialize individual ramzswap devices using the rzscontrol utility.


3. Activate: Use the swapon command to activate specific ramzswap devices.


4. Check Stats: Use rzscontrol with the --stats option to monitor the performance of ramzswap devices.


5. Deactivate and Reset: Utilize the swapoff command to deactivate ramzswap devices and reset them as needed.


6. Unload Modules: Use rmmod to unload the ramzswap, lzo_compress, and lzo_decompress modules when required.

If encountering compiler errors during installation, ensure the kernel source package is installed, such as 'kernel-devel' on Fedora.
