Question Publishing posts extreamly slow - Kunena 4.0.11

After doing some testing I 'think' a plugin conflict can be ruled out. I renamed the original /plugins directory to pluginsXXX.
Then I created a new /plugins directory - added inside it two directories /kunena and /system/kunena - with all the files needed to make kunena work.
Still, when I submit a post with only a few lines of text it still takes 15-30 seconds to complete. I don't understand it. Everything else on the entire website is really fast. Any additional help or suggestions would be really appreciated.

update joomla to Joomla! 3.6.2

Thanks. I didn't know an update was available. I'll do a backup and give 3.6.2 a try to see if it solves the problem.

I upgraded to Joomla 3.6.2. No help with the problem of submitting post taking a really long time. I'm posting my Kunena configuration report again after the update. Maybe you can spot a problem that would cause submitting a post to be so slow (15-30 seconds).
Thanks for your help.

The Kunena configuration "Forum E-mail Address" field has the default Joomla email address in it. Are you suggesting I use a different email address for the Kunena configuration?
