The application won't run any faster than the code that serially parses

The parsing isn't a bottleneck. It currently sends over 6,000/min and we
had to actually slow it done intentionally because IIS's SMTP server was
backing up. So I don't think that's an issue. However, if we just
relaying
the message to the posfix machine,
Postfix can accept mail via SMTP very quickly.
I"m not disputing this fact. I used smtp-source with 10 connections.
Without DKIM signing - 14,634 emails/min
With DKIM signing - 4,762 emails/min
I think we would both agree that that's a large discrepancy.
the rates will not hold up either based
on my testing with smtp-source using DKIM,
This is a waste of time unless you can identify the bottle-neck in your
tests. How are you doing DKIM signing? Are you running out of CPU, ...
I'm using DKIM-milter. During the testing, the CPU nevers goes over 3-4%
.
so that's why I'm asking if
local submission would be any faster?
Not until you find out what's slowing you down. You may need to pay
someone (good) money to figure this out for you. This is an advanced
problem, and few on the list have both the skills and the time to
debug this with you.
hahah ok. Thanks for your high level expertise.
