Speed up Ubuntu Linux with Swap Fine Tuning
Speed up Ubuntu Linux with Swap Fine Tuning Swapping is designed for Low memory systems. Now a days plenty of RAM space available. RAM is much faster than HDD. Swap uses Hard disk space as virtual RAM. If you reduce the usage of HDD and increase the usage of RAM will boot the performance of your system. The parameter named swappiness controls the tendency of the kernel to move processes out of physical memory and onto the swap disk. swappiness can have a value of between 0 and 100 swappiness=0 tells the kernel to avoid swapping processes out of physical memory for as long as possible swappiness=100 tells the kernel to aggressively swap processes out of physical memory and move them to swap cache The default value of swappiness in Ubuntu is swappiness=60. Reducing the default value of swappiness will probably improve overall performance for a typical Ubuntu desktop installation. For Desktop users A value of swappiness=10 is recommended. For Server , it is ...
