<para revision="269846">The default &man.zfs.8;
<acronym>ARC</acronym> hash table size has been increased,
and a new &man.loader.8; tunable,
<literal>vfs.zfs.arc_average_blocksize</literal>, has been
added. Previously, the hash table could be too small, which
would lead to long hash chains and limit performance for
cached reads. The
<literal>vfs.zfs.arc_average_blocksize</literal> tunable
allows overriding the default block size. The previous
default was 65536, and default of the new &man.loader.8;
tunable is 8192.</para>
