I would like to share with you on a useful tool that I found recently! It is Minimem.
Quoting from the Minimem site,
Initially developed for Firefox only, Minimem now can reduce the memory footprint of any application. It runs in the background and can be set up to optimize as many proceses as you’d like, using a very intuitive graphical interface. Unlike other memory optimization tools, it gives you full control over what applications you want to optimize, when and how often, as well as the possibility to only optimize memory when required and relevant.
It optimizes memory by removing as many non-necessary memory pages as possible from the selected processes. It does so at regular intervals which can be user-defined as well and every 30s by default, though uses an advanced pooling mechanism to ensure the CPU usage of Minimem remains low at all times. This then optimizes your applications which can load those pages back whenever they need, and makes your overall system perform much better whenever it is memory limited.
Minimem can be download from its official page here.
So far, I am happy with this tool!
