Xenforo 2.2.8 response time of the forum is slow

hongtrang · Dec 4, 2021

After I upgraded to version 2.2.8, the response time of the forum was quite a lot. I use webpagetest.org to test, First Byte Time (back-end processing): 37/100 (score F)

Before in version 2.2.7 P1, my First Byte Time always got an A.
I made no changes on the server side, is this a bug of Xenforo 2.2.8?
My config.php

Code:

$config['enableMail'] = true;

$config['fullUnicode'] = true;

$config['enableListeners'] = true;

$config['enableOneClickUpgrade'] = true;

//Used: br

$config ['enableGzip'] = false;

//Memcached

$config['cache']['enabled'] = true;

$config['cache']['provider'] = 'Memcached';

$config['cache']['config'] = [

'server' => '127.0.0.1'

];

//Page Cache

$config['cache']['enabled'] = true;

$config['pageCache']['enabled'] = true;

$config['cache']['context']['page']['css']['provider'] = 'Memcached';

$config['cache']['context']['page']['config'] = ['server' => '127.0.0.1'];

$config['pageCache']['lifetime'] = 600;

My server has both Zend OPcache and Memcached setup. First Byte Time got an F after I upgraded Xenforo 2.2.8

No problems here with 2.2.8:

Before that when I was in 2.2.7P1 everything was normal (score A)

In addition, on my server there are a few other sites running. Those sites all scored A

Try https://gtmetrix.com/ and look into the details. Should give you an idea why you are getting low(er) scores.

No problem with 2.2.8 here on 2 forums with Litespeed

If you’re behind Cloudflare they have seemingly had issues today but are resolved now.

Aside from that, nothing I can pinpoint would cause this in 2.2.8 so that is likely just a coincidence plus we’ve not had any other reports of that so far.

Thanks!
But
Cloudflare - I only use DNS

However, I don't understand why when I host on the same server, my other sites don't. Only my forum is suffering from this situation

Other domains (subdomains) I also only use DNS of CF

Yeah probably not Cloudflare then but highly unlikely to be caused by any changes in XF as far as I know at this stage.

You’ll need to try the XF default style and disabling all add-ons at least first.

If you enabled Xenforo debug mode before upgrade to take some measurements and then after upgrade, you could compare the debug time/queries to see where you differences are.

Looks like Memcached doesn't work with my site.

Done!
I have solved the problem.
I don't understand why the Memcached configuration in the src/config.php file doesn't run in version 2.2.8 (previously in version 2.2.7P1 it still works fine).
I have corrected it as follows:

Code:

$config['cache']['enabled'] = true;
$config['cache']['css']['enabled'] = true;
$config['cache']['provider'] = 'Memcached';
$config['cache']['config'] = [
    'server' => '127.0.0.1',
    'port' => '11211'
];
$config['pageCache']['enabled'] = true;
$config['pageCache']['lifetime'] = 360;
$config['cache']['context']['page']['provider'] = 'Memcached';
$config['cache']['context']['page']['config'] = [
    'server' => '127.0.0.1',
    'port' => '11211'
];

Thanks everyone!

You mean adding 'port' => '11211'?

Yes

It's strange

I also don't understand why it works fine at 2.2.7P1 but upgrade 2.2.8 it doesn't work when missing port 11211

rdn · Dec 4, 2021

Maybe XF Devs can answer that :|

Chris D · Dec 4, 2021

Well, given that the port number being added will do precisely nothing, that isn't what fixed it.

You can change the port value to anything, it won't have any effect. We literally don't use it in the code.

Chris D · Dec 4, 2021

FWIW if you ever did need to change the port to something non-default then the syntax would be:

PHP:

$config['cache']['config'] = [
    'server' => [
        ['127.0.0.1', 22122]
    ]
];

(It accepts an array of servers, so you can configure multiple servers if needed).

Why do we need so many extra config options? Some seem redundant.

Forgetting the "Memcached" issue, I see nothing for Opcache or to deal with JIT compiling of PHP 8. Are there any?

You don't need them - they're optional.

They're detailed here: https://xenforo.com/docs/xf2/config/
