Summary

Release Note

Rationale

The RAM requirements for running an ubuntu desktop are currently very high. Especially on LiveCDs and Thin Clients this high demand is noticeable. Additionally there are more and more users with low specced subnotebooks within the ubuntu userbase that have a requirement for being able to run the system on a limited amount of memory. With the Google Summer of Code project [http://code.google.com/p/compcache/ compcache] it is possible to extend the available physical ram with a virtual swapdevice, this technology will be included in ubuntu.
