You got my attention on this one.

I reverted to 2.11.16 quite some time ago because it could send out 25,000 emails about 180kb in size in about an hour, which is about 7 per second. I needed the speed because sometimes I send several in a day.  Subsequent versions took much longer to send.  I'd like to have the advanced features of the newer versions and would update in a heartbeat if the speeds were comparable.

FYI: using sendmail, no batches, no gaps; just one big gulp.  It's faster than smtp sending for this particular version.

Hello Everyone,

I've been toying (again?) with changing the template engine in Dada Mail (but keeping the syntax the same) from HTML::Template:

http://search.cpan.org/dist/HTML-Template/

To HTML::Template::Pro

http://search.cpan.org/dist/HTML-Template-Pro/

HTML::Template::Pro promises speedups between 10 and 25x over HTML::Template, which is pretty nice. The downside is that I won't be able to ship Dada Mail with HTML::Template::Pro enabled by default, as HTML::Template;:Pro requires you to compile the module. I can still make it an option for those looking for a speed/memory use improvement.

Doing a quick test, I'm able to see around a 10x speed improvement over what is currently being used when making HTML screens in Dada Mail, and a 2.7x speedup for parsing templates in email messages.

That seems a fairly good improvement, but the initial speeds of HTML::Template aren't super slow - for HTML screens, we're talking about .025 seconds to render the screen with HTML::Template, and .0025 seconds to render the screen with HTML::Template::Pro. I'm not sure of memory usage, but I'm guessing that memory using is lower with HTML::Template::Pro.

You can follow this part of the project here:

https://github.com/justingit/dada-mail/tree/features-html_template_pro

And actually, all the different sub projects I have happening here:

https://github.com/justingit/dada-mail/branches


Looks as if v4.9.0 is going to be a big release.
