Are you sure? At some point data has to get flushed from the cache to
the drives themselves. In most

we've been wondering around here as to what the average is
To answer your question Yes I did expect the same or better performance than
standard UFS based on all the hype and to quote Sun Blazing performance
ZFS is based on a transactional object model that removes most of the
traditional constraints on the order of issuing I/Os, which results in huge
