Before we have Matt, who can work full-time on clustering - the _purpose of this project_ - digress for months on filesystem performance, can we quantify the actual problem? Corecode's report is the only one we have, and we don't have a realistic test scenario that measures when it happens or how much it happens. I've been running pkgsrc bulk builds on Hammer disks for quite a while now, and I have not seen any noticeable change in overall run time from using UFS to using Hammer. Chasing a heisenbug can be very difficult.
