Mail shouldn't be affected by the datastore, though other users are
reporting general deadline issues with email delivery.
I'm looking into the issues with email, but there's no guarantee that email
is instantaneous - it just so happens that email performance has improved so
much that we have come to expect it. 15 minutes seems wrong, so there might
be something going on, but I think it is commercially reasonable to expect
an email delay 5 minutes, with the 90th percentile of emails being
delivered in under 2 minutes or less.
Do you have any information about the dates or times when email seems to be
slower?

Hi,
Lately, for my app (id: anothersocialeconomy), I've started to notice
that many mail messages are delivered after a long delay.
Usually, when I can reply to a generated message, I get a feedback by
email in a matter of seconds. In GMail, I see the yellow box in bottom
right corner announcing the new message and offering a link to show
it in the context of the thread.
Now, it happens that some messages are only received after a long
period of time, 15 minutes and plus, which is very annoying :( I've
been able to verify in the logs that the messages is correctly sent
(no error reported, no timeout). I don't know if the issue is in the
SMTP queue, if it's just after the javax.mail.Transport.send() call,
or if it's related to the email accounts (all issues I've identified
were related to GMail recipients)...
Maybe it's related to the latest reported latencies in the datastore

Any idea?
A+, Dom
