APCu cache support

[masmo]

I would like to activate the APCu cache but if I configure as in the guide the site does not load.

Cache support - XenForo Manual

End-user documentation for XenForo

xenforo.com

Does xenForo support APC but not APCu?
Thanks

APCu is not APC, so following instructions for APC won't give you support for APCu. Internally there is support for APCu though, so maybe as simple as specifying the right provider (ApcuCache)?

APCu is not APC

Opss

Thanks for your help

I tried with

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

but I always get error 500 and the site does not load.
I'm sure APCu is active on server...

if I want I can also use Redis, do you recommend APCu or Redis?

Never even heard of APCu, I just know APCu isn't APC. Beyond that, I have no idea... never used it.

How about just apcu?

Recent PHP versions come with opcache. I just wonder the value of adding more compression components to the mix.

Nothing, it doesn't work...

 

[Gene Steinberg]

Please verify that apcu is installed in your system and activated.

I also tried with another software, it recognizes APCu and works correctly.

Looks good to me. I'll leave it to the XF gurus to help you figure it out.

As I said, I since you have opcache installed already, maybe just looking for online instructions to optimize it will deliver a decent performance boost. There's also nginx proxy and caching, available on cPanel and Plesk installs. Indeed, the latest versions of Plesk have a Performance Booster feature which lets the control panel figure out the best settings for you, so you don't have to worry about it.

You are right


I will look for some tutorial to optimize

There's also nginx proxy and caching, available on cPanel and Plesk installs.

Unfortunately I can't access cPanel

Many thanks

What control panel does your host give you?

 

[Jeremy P]

In XF 2.2, only regular APC support is available. XF 2.3 will have support for APCu, but frankly I'd recommend just using Redis these days.

It has a panel created by them, there is no cPanel or Plesk.

@Jeremy P OK then I activate Redis

Thanks everyone for the help.

Opache is a completely different beast from APCu. Opache caches tokenized (compiled) PHP code, PHP fixed strings, and PHP file loads. APCu is a data store only, where Xenforo can store data to have fewer queries sent to the MySQL database.

So one does not displace or replace the other.

APCu is basically APC without an opache cache since PHP now includes Zend's "opcache" plugin.

Is it still the case that XenForo 2.3 supports APCu? If so, how would you enable?

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