Are these queries all from the same page? Or many different pages?

BTW it would be easier to put all this into a text file rather than posting so many comments. You can use pastebin.com for that.

---

Are two different pages.
You can find out what is wrong, Scott?

Answer 1

Here are some of the things I notice about what you've posted:

1. Many of the slow queries you posted (like the first qa_options one) are standard queries that normally run fast. They are probably only running slow because of the high load.

2. The vast majority of the load time looks to be in the Setup. The 2 main things that are loaded in Setup are login modules and any process modules that handle "init_page". So take a look for any plugins using those, they could be the culprit.

3. You have a ton of queries like
    SELECT title, content FROM qa_userprofile WHERE userid=(SELECT userid FROM qa_users WHERE handle='Enis Junior' LIMIT 1)
That looks like a plugin is running multiple queries in a loop. That query comes from the Q2A function qa_db_user_profile_selectspec, but that is not used in a loop within Q2A at all. See if you can find which plugin is doing that.

4. Also as I suggested previously, you should find that using the option QA_OPTIMIZE_LOCAL_DB in qa-config.php will increase performance for you.

Hi Scott. Thanks. 4 plugins use qa_db_user_profile_selectspec:
Question Followers widget
Follow Users
My Followes Widget
Category Followes Widget

None plugin has qa_register_plugin_module('process' in qa-plugin.php

---

Hmm, looks like those plugins are not available any more, so I can't really suggest any improvements, sorry.

---

Thanks, Scott. You helped a lot.

I delete from my server 4 plugins and the problem continues to happen.
