Hello, I'm currently try to delete a directory with more than 50k entries on a heavily loaded server. Wondering why this takes so long I straced "rm" and found out that only 2..3 entries are unlinked per second. This really slow rate is, I suppose, due to the fact that metadata updates are made disk-synchronous. This is, for my application, not necessary. I can live with large metadata changes batched into one large transaction. Is it possible to switch off synchronous metadata updates (while the filesystem is mounted) so that those changes are reflected only some times later or when I switch off asynchronous metadata updates? Xu�n.
