you can have w3tc on with the forum, you just need to tell it to ignore the wp page the forum is on... if you leave the forum cached, users will not see the latest data and you will have all sorts of js/jquery issues...
On your site now, I see the page caching is disabled - good... but the database caching, cdn and other caching still running...
hard for us to debug when its cached...
btw, what kind of hosting do you have? most ever online in the forum is 140 users... that is not a large number and most hostings should handle that kind of traffic across all of a wp site including the forum...

Everything is hosted on linode. I dont think that the forum page is cached... it's in my exclusions. Are you absolutely 100% certain that it is being cached?

With w3tc there is an exclusion list for each cache type. Did you enter the exclusion for each cache type or just on the page caching exclusion.

That's a great question. I will add the same exception to the other caching types, but the issue persisted when w3 was off entirely. That said, even though I DELETED nginx helper, it's still showing me a caching message in the page source. My developer sent this support request to the mod of the nginx forum if this helps clarify:
This HTML comment has persisted through full server reboots, nginx restarts and reloads, and a move to different physical hardware. It’s almost as if the HTML itself has actually been modified.
Nginx does have the
module enabled, but we’re not doing anything with it — W3TC is handling caching here.
Here’s the Nginx config: https://gist.github.com/willie.....71572abc6e
Please advise and/or email me directly, and thanks very much for your help in advance.

Can I also refer you back to my earlier post (#5) where I did suggest you set up a member account for us so we can inspect the polls page you linked to.
Please PM credentials to both myself and to 'Mr Papa'. Please include in the PM a link to your site, a link to this thread and brief reminder of the problem. And one of us will take a look at that page.

I have new interesting stuff for you:
That nginx helper comment is (was) stored by simplepress forum software in its database!

There were 3 such posts. I am not sure how this can happen. But I fixed them anyway.
Most likely simplepress has something like ob_start and/or not using wordpress admin_ajax.
I will also check nginx-helper but these comments has nothing to do with performance fall or caching.
For the matter of fact, even I removed them now, you won't see any relative difference in performance.

Curious indeed to understand how all this nginx crap can get itself included in a simple html POST variable. Would be nice to know.
I seem to have received a PM from you but when I loaded up your forum page it is still being served up by the total cache plugin...

Yes, once we got the nginx message off the site, we wanted to experiment with what we could get away with. The forum has been loading INCREDIBLY slowly, and with that form of caching enabled, I was still able to cast a vote on a new poll and tag someone in a post. I'm not sure what ends up breaking as a result of caching, but the forum is virtually broken without it.
I'm not sure if it's fully working right now since the cache has had some time to build, but I can check. Either way, the nginx message is gone so I can actually shut of w3 when we need to diagnose a problem and test it out.
