The directories on the single mount point that I am referring to are varied in depth and density - but some of them have as many as a few million inodes in them and can go 5-10 levels deep. But that is not a rule - it is a large multi-user system (think old school shell server) with hundreds of users that can populate their home directories with anything they want. The only thing I can say for sure is that I am using 2.5 TB of space (out of 8 TB) and am using 23.8 million inodes. So it's not that dense with inodes at all, but there is no telling how even a distribution that is - a cp/rm target might not be represented well by the average (ie. they might be very sparse or very dense) So again, all is well, but I have these long 'cp' and 'rm' processes that I would like to speed up, if possible. All else being equal, how do you optimize a system for copying from one place to another on the same mount point ? How do you optimize a system for fast file deletion ? Are the two mutually exclusive ? ____________________________________________________________________________________ Luggage? GPS? Comic books? Check out fitting gifts for grads at Yahoo!
