This option allows archivists to publish incomplete archives
with only new mail while allowing NNTP article numbers
There is no automatic way to use reserved NNTP article numbers
when old mail is found, yet.

+It can be useful to use a single shard (C<-j1>) for inboxes on
high-latency storage (e.g. rotational HDD) unless the system has
enough RAM to cache 5-10x the size of the git repository.
-It is generally not useful to specify higher values than the
-default due to contention in the top-level producer process.
+Another approach for HDDs is to use the
+L<public-inbox-index(1)/publicInbox.indexSequentialShard> option
+and many shards, so each shard may fit into the kernel page
+cache. Unfortunately, excessive shards slows down read-only

+For fast storage, it is generally not useful to specify higher

+Do not store document data in Xapian, reducing Xapian storage

-This tool predates NNTP support in public-inbox and is missing
-C<newsgroup> and many of the options documented in
-L<public-inbox-config(5)>. See L<public-inbox-config(5)> for all the
-options which may be applied to a given inbox.
+Some of the options documented in L<public-inbox-config(5)>
