XenForo + caching = AMAZING

[imspot]

I am using this:

$config['cache']['enabled'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions'] = array(
    'caching'                  => true,
    'automatic_serialization'  => true,
    'lifetime'                  => 1800,
    'cache_id_prefix'          => 'xf2_'
);
#Memcached
$config['cache']['backend']='Memcached';
$config['cache']['backendOptions']=array(
      'compression'=>false,
      'servers' => array(
              array(
                  'host'=>'localhost',
                  'port'=>11211,
              )
        )
);
$config['cache']['cacheSessions'] = true;

I've added this into config.php and after forum refresh i'm getting blank page with this error:

An unexpected error occurred. Please try again later.

And error log says that Zend_Cache_Exception: The memcache extension must be loaded for using this backend ! - library/Zend/Cache.php:209

Solution?

Does memcache work with FCGI php handler?

It works fine with ZEND OpCache - I use it on all 3 of my forums that way.

Make sure that memcache/memcached are loaded in your PHP processor and that the memcached daemon is running?

 

[imspot]

Still not working

 

[TPerry]

Is this a VPS/dedi or shared hosting? If VPS/dedi centOS or Debian?

 

[imspot]

VPS hosting with centOS

 

[imspot]

Is there anyone who knows the solution for this. My host cannot get memcached to work. It is installed but it is not showing in phpinfo

 

[TPerry]

To elucidate further, he is running a VPS with WHM/cPanel. It DOES show as installed (I even SSH'd into his system to confirm memcached was installed and running - it is, and that the memcache module was installed - it's listed in the php.ini).
He's using centOS and Apache with fcgi as the php processor.
The "simple" routine of clicking the correct buttons apparently isn't working. What's weird is that his php info page does not show geoIP module installed, but apparently it is working (I saw where it was installed in the apache setup as a module).

Does memcache (and related type modules) need to be installed in apache also on a WHM/cPanel setup?
I'll be the first to admit I hate panels for this reason. Several instructions showed to install memcached PECL also, but when you select it there are apparently outstanding dependencies that are not met and the compile does not complete.


EDIT:

This is now fixed... turns out the existing php.ini had a bad string in it and was not being read.
After fixing the string here is what now shows up.

 

[imspot]

Great and yes it works now!

My Zend opcache keeps refreshing every 15-20 mins or so. I tried APCu with it but xenforo wont use it

Does anyone know how to keep zendopcache from refreshing every now and then? I have turned on piped logging aswell so its not apache restart and I am using Fcgi as handler. Any ideas? Or is this how it is supposed to be?

I am going to try installing memcached and see how it goes with zendopcache.

-------------------
Update: I installed Memcached and its working well.

Zendopcache+Memcached is a little faster then APC but my problem of zendopcache refersing every 20-30 mins is still not resolved so I would appreciate if some one could tell me where to look for a solution.

 

[Slavik]

Can you post your current config settings for zend

 

[Parminder Singh Chahal]

These are the settings I have at the moment :

-------------

zend_extension="/usr/local/lib/php/extensions/no-debug-non-zts-20121212/opcache.so"
opcache.enable=1
opcache.enable_cli=1
opcache.memory_consumption=10240
opcache.interned_strings_buffer=512
opcache.max_accelerated_files=50000
opcache.max_wasted_percentage=10
opcache.use_cwd=1
opcache.validate_timestamps=1
opcache.revalidate_freq=259200
opcache.fast_shutdown=1

-----------------

My opcache refresh problem is solved but it had nothing to do with the settings I had. I was using Fcgi and now I have removed that and use php-fmp using a plugin someone made for Cpanel. It has been up for days now without a refresh.

When I say faster I dont mean to say that Ive measured anything, it just feels faster and more quick to respond thats all.

How can I config both APC and Memcache in my config.php file?

How can I config both APC and Memcache in my config.php file?

A question I also have. I have memcached working, but if installing both would increase performance further, that's what I would like to do.

The newer php releases already have a very fast cache.

What the newer php releases do not have, is a user cache. You can use these user caches:
- memcache
- APCu. The regular APC consists of the cache mechanism that is already included into the newer php releases, plus the user cache. APCu means "APC, just the user cache from APC"

There is no need to enable them booth as xenforo only can use one of them, either APCu or memcache. If you have a single server, APCu is a bit faster (although more unreliable). If you use multiple servers, memcache is great as you can have an additional server just for memcache and every server can reach out to this dedicated cache server. That is not possible with APCu.

I use redis on mine instead of memcached or apcu.

Works great

Yup using Redis caching with Xenforo as well https://community.centminmod.com/posts/18863/

XenForo + Redis caching is GREAT! w/ @Xon addon

OK, I will share my own experience also .

What tool is the screenshot from? Are you using any other cache systems?
