I see from the documentation that the current default of
hash_queue_names is only to hash the defer and deferred directories, in
contrast to versions prior to 2.2 where pretty much everything was hash
queued. The documentation has this to say about the reason for the change:
Claims about improvements in file system technology suggest that
hashing of the incoming and active queues is no longer needed. Fewer
hashed directories speed up the time needed to restart Postfix.
My question is: if the time taken to restart Postfix is not an issue,
but throughput performance while Postfix is running is a primary
concern, is it still worth hashing the incoming and active queues? If
so, does anyone have any comments to make on the performance trade-offs
involved in either hashing or not hashing the queues?
