I've got 17,500 e-mail messages in my Inbox on a Cyrus 1.5 system (that is old), and have not seen this problem. It could be filesystem and kernel related. ext2/3 has historically not been good at this, but is better now. ufs is actually pretty good, but mainly because BSD kernels cache so much vnode data, it does not matter if the directory is hashed on disk or not. And you always want "noatime" enabled on your Cyrus spool, no matter the filesystem or OS, or version of Cyrus.
