=item B<-chunksize> <I<chunk size>>
Sets the size of each cache chunk. The integer provided, which must be
-from the range C<0> to C<30>, is used as an exponent on the number 2. It
-overrides the default of 16 for a disk cache (2^16 is 64 KB) and 13 for a
-memory cache (2^13 is 8 KB). A value of C<0> or less, or greater than
+from the range C<0> to C<30>, is used as an exponent on the number 2. If not
+supplied, a default chunksize will be determined based on the cache type and
+cache size, and will range from C<13> (8KB) for memory cache and C<18> to
+C<20> (256 KB to 1MB) for disk cache. A value of C<0> or less, or greater than
C<30>, sets chunk size to the appropriate default. Values less than C<10>
(which sets chunk size to a 1 KB) are not recommended. Combining this
argument with the B<-dcache> argument is not recommended because it

Specifies the number of entries to allocate in the machine's memory for

+is not specified, the number of stat entires will be autotuned based on the

=item B<-volumes> <I<number of volume entries>>
Specifies the number of memory structures to allocate for storing volume
