What we have observed that it is constantly stuck at cache_swap_low. If we purge the cache it starts to work fine again until cache hits cache_swap_low mark. That's because the I/O load almost doubles then.. removing content from a filesystem is nearly as expensive as writing it in the first place. Regards Henrik
