Is it truly worth pruning? I mirror the freebsd repository, mail archives, and www site locally: size 1.9Gig. time 4:48min about 2/5 gig per minute ie: it takes about 5 minutes for the update to run. Most of that time is due to the mediocre link I live behind. Internally, we maintain a CVS repository which we use cvsup to backup (100T x-over direct between machines). size 57Gig (no, that isn't a typo). time 41:36 about 1.3 gig per minute In the above case, the network is not the bottle-neck. We simply can't read the data off the disk(s) fast enough (currently a dpt raid, moving to amr with more than twice the performance). I guess I don't see why it's worth pruning. The network connection in my case seems to be the bigger problem. Pruning the tree isn't going to buy me anything. And, we lose information... Comments?
