I'm no expert, but it strikes me that OPENING maildir mailboxes on ANY filesystem will ALWAYS be slower than mbox, because of what you need to do. An mbox mailbox will generally have little fragmentation on most Unix-like filesystems, so when you open it (in the mailbox sense, as opposed to the filesystem sense, i.e. to get all the headers), it will be something like this: open read read read read close Whereas a maildir format mailbox has many small files, which could be anywhere on the disk partition. So when you open one, you have to go through these contortions: open read close seek (the disk heads, not the syscall) open read close seek open read close seek I can't see how this could ever be fast... -- Derek Martin [EMAIL PROTECTED] --------------------------------------------- I prefer mail encrypted with PGP/GPG!
