phpBB3 slow and internal dummy connection

Using Apache 2.2 and PHP 5.6 PHPBB3 is very slow to respond.  Actually for some reason it takes so long to even register a log entry in access_log as in several seconds or a few minutes later it shows up in Apache.  All other vhosts and Apache access stops working and freezes until the request to access PHPBB3 slowly completes.

It seems to randomly be slow if you stop using it whether for posting or reading the forums.  I've migrated to different machines including SSD and the problem has not changed at all.  Some have posted that the internal dummy connection means Apache is killing off dead workers.

I've never had an issue like this with any PHP app except PHPBB3

this issue is accompanied by a delay in any logging activity of a few minutes and then suddenly it loads the destination page and a cron script:
