Yeah I meant removal time :) I found this article[1] that suggests that over time the ext4 fragmentation can cause a performance drop that is very noticeable on hard drives. I'm trying to determine how fragmented is the sdb1 file-system, by running e4defrag and e2freefrag[2], but I'm not sure if they will complete soon. Copying and removing /gnu/store/trash on the SAN will be interesting but the ultimate test would be to be able to re-create the ext4 file-system directly on Berlin's sdb drive to evaluate the fragmentation role in this funny business.
