Hashing does not slow down deliveries.
|
|
|
|
However the problem is scanning an empty deferred queue. On an idle
|
|
machine, it takes some 5 seconds to scan an empty depth=2 deferred
|
|
queue unless the blocks happen to be cached. During those 5 seconds
|
|
the queue manager will not pay attention to I/O from delivery
|
|
agents, which is bad.
