If you just do edits of files it probably does not matter too much what fs you use. Booting the machine seems like one activity that many users end up waiting on the FS for. Yes? Starting up complex and big applications like xemacs and mozilla would be another. Yes? Others? Hans PS reiser4 performance is up a lot recently, and within two weeks I think cp -r will have been optimized as much as is worth doing. cp -r accesses files in readdir order, and that does indeed seem worth optimizing, but soon we will need to optimize more sophisticated access patterns than that.....
