While working with my new Hurd system this weekend, I noticed that there seems to be quite a bit of disk I/O for even very simple activities. For instance, while editing files in vim, I notice that each keystroke I make (while writing -- not just moving the cursor) is mirrored by a "tick" noise from my hard disk (i.e., a write action is occuring). Does anyone know if the Hurd implements any form of Caching? -Brent
