Over the last few weeks my Fedora 8 machine has been running extremely slow. Applications like Firefox constantly freeze up and I am seeing sustained spikes in CPU activity while carrying out typical tasks (browsing the web, compiling Java programs, running subversion operations etc). This all started happening suddenly, the machine was running fine for the past year and now it is frequently crawling.
I am looking for suggestions as to what may have happened to cause this. Maybe a list of possible explanations that I can look into?
