During this period of time, i "felt" some slowdowns after prolonged use (system gaining latency over time). I remember seeing a schedgraph of the linux/bsd boot process, so my question is, would it be possible to generate a schedgraph at a certain interval of the entire running system (everyday)? I can see how this kind of data would aid in the development of the ULE scheduler. -Julio
