Send mail make slow Q2A system.
if in admin pannel > emails checked Email this address when a question is posted
Case
-
Someone posting a questions. (send mail to Admin )
-
comment ( send mail owner )
-
select answer ( send mail answerer)
-
etc
I tested both use default php mail() function and smtp with gmail server. Both is too slow.
default php mail() function delay almost 7~10sec. smtp with gmail, too
if unselected notification, all is fast
So I think, to solve this problem AJAX send mail is needed.
Help me ;p
