I think you may be hitting what people say that reiserfs doesn't scale well. Let me see if I can find a reference... ah, here: <http://lists.opensuse.org/opensuse-factory/2006-09/msg00542.html> [Jeff Mahoney] ] ReiserFS has serious scalability problems. David Chinner's talk at OLS ] really underscored the problem well for a single, large, high bandwidth ] file system. While I realize that XFS-style scalability isn't a real ] goal for most users, ans isn't a target workload for reiserfs, the ] scalability problems are real. ReiserFS uses the BKL for synchronization ] everywhere, and since it's system-global lock, the problem doesn't go ] away when you split the file system into smaller ones. Lock contention ] alone is one problem, but it's made worse by cache bouncing between ] processors on larger systems. - -- Cheers, Carlos E.
