The Kunena team has announce the arrival of Kunena 6.4.13 [6.4.13] in stable which is now available for download as a native Joomla extension for J! 5.4.x/6.0.x./6.1.x. This version addresses most of the issues that were discovered in K 6.2 / K 6.3 / K 6.4 and issues discovered during the last development stages of K 6.0 Hint: This version is primarily intended to facilitate an upgrade if Joomla was first updated to version 6.1 before Kunena was up to dated.
Topics that are moved into this category are generally considered to be closed. Users may want to add additional information but these topics should not be resurrected in order to discuss new problems or unrelated matters.
If there are a lot of users subscribed to a particular topic or category, each of these users gets a notice of a new topic (assuming unmoderated). Kunena processes these emails once the user post their topic. With a lot of subscribers this suspends the users session for quite some time while Kunena sends the emails.
Is there a way to queue these and process them in the background? How have others handled this problem?

Thanks Rich, that definitely seems to help. As I am using an external smtp relay service (Mandrill), and I had this value as zero, I think Kunena (through Joomla) was sending each email as a separate smtp session and this was taking forever. I changed the value to 50 and this really made it faster. We have at most 250 subscriptions so 5 smtp sessions versus 250 is a big difference.
I just discovered this setting, and it made our forum much more responsive. We were actually getting internal server errors because it was taking kunena so long to process the notifications.
