How to eliminate excessive queries from addons?

I have 122 mods installed on my forum, and now my forum index runs 80 queries, with a lot of them SELECTing from template_compiled and a fair share of SELECT * FROM xf_node WHERE lft > ? AND rgt < ?. Is there a way to compress these queries so I only need to run 20 instead of 80, without any code edits?

Thanks.

Enable templates as files and make sure you are using an opcode cache such as xcache

A lot of it is likely due to the arguable oversight in the template system, where multiple calls to create the same template (such as a template hook inside a foreach loop) do not provide even per-request caching and will perform identical select queries several times.

I was hoping to see the list of add-ons to jog my memory of a add-on clash I saw myself which caused these extra queries. I've just remembered what the add-ons were.

The clash was between Nodes as Tabs and Digitalpoint Ads Positioning. I think, specifically, the fault was with Nodes as Tabs so...

If you have old versions of these, especially Nodes as Tabs, then update them to the latest available version.

Jesus thats a lot of addons. Enable debug and see which ones are adding the largest numbers.
I do have debug on, but looking at all 80 is a pain... I also have no idea how to tell which ones are adding - they all contribute. But I see this one a lot:
Code:
SELECT moderator_content.*, user.username
FROM xf_moderator_content AS moderator_content
INNER JOIN xf_user AS user ON (user.user_id = moderator_content.user_id)
 
WHERE (moderator_content.content_type = 'node') AND (moderator_content.content_id = 24)
ORDER BY user.username
(Also, I wish I didn't have to install that many addons, but that is how many features XF is missing... sigh. *insert IB rant here*)

Even if we don't have memcache,xcache,apc, etc?
In this situation it's all about choosing the fastest path from ram into the php parser. Unless you have a highly optimised mysql server with adequately large innodb pool on the same box (or with very low latency link), or almost no 'free' ram being used for os cache, then files will be faster than mysql.

Obviously any opcode cache is the fastest by a long shot - much higher chance of fetching from ram than the alternatives, and less work for the php parser as well.

Admin Search User IP 1.0.0 < prefer the built in feature <- My staff come from vBulletin so this addon will save them some time... keeping.
Clickable Rows 2.0.0 < I think this can be done with manual edit <- Yes, but since there are two templates and one js file... I'll probably leave it.
Custom Footer customFooter < Modify it yourself, not by an addon <- Looks confusing for other admins to modify the content... will leave it for now.
Developer Kit 1.1 < Are you a xenforo developer/programmer? <- Yes, but not sure why it slipped in my production site.
Digital Point Spy 1.0.5 < Could be resource hog <- No additional queries detected... turning it off doesn't really slow performance
Find users sharing the same IP 0.0.2 < Use the built in feature <- This is built-in? Where? (If you mean ACP I need it to be readily accessible from postbit)
Floating Login by SolidMean 1.0.0 < Can be done by adding 2 lines of css code on extra.css <- How? The code shows that a whole template is needed but uninstalled anyway.
Separate Sticky and Normal Threads 1.0 < Can be done with template edits. <- Read the code, not sure how.
Signature Restriction 1.2.1 < redundant, you have FreddysHouse Tools: Signature Once 1.2.0 already <- Not redundant, Signature Restrictions adds permissions
[dc] Smiley Manager 1.1.0 < redundant, you have Smilie Importer by Waindigo 1.0.1 already <- Not redundant, Smiley Manager adds Smiley Categories

And many more addon's to point.
