Zend Redis Cache 1.6.0

[TPerry]

remi repo has redis 3.0x which is needed

That's what I get for assuming... I "thought" REMI was already in the repo list.... it's EPEL that is!
Working now. Now to see how it compares to memcache(d).

nope REMI is disabled by default see http://centminmod.com/yum.html

We have switched to Redis too after 2 years with memcached.

Redis looking better. I hope, we won't see any error during any process on forum. Until now, standart pages are faster and no problem. But we must see forum software upgrades, style/language changes, rebuild process etc.

Thank you for that great add-on. We are waiting changes ..

@Xon, any thought about this?
Only 6 errors similiar to that come this morning, same minute all 6. No redis regarded errors before or after this

I've mostly seen this occur when Redis is stalling due to disk IO in a contested virtual environment.

Can you post the "SAVE" statements or the append from your redis.conf file?

You can use the AOF (change log) persistence rather than the RDB (dump) persistence.

appendonly yes
aof-rewrite-incremental-fsync yes
appendfsync everysec

Alternatively, just disable persistence all together or periodically do RDB snapshots when you know the site isn't as busy (ie use cron & redis-cli)

Xon updated Zend Redis Cache with a new update entry:

Maintenance update

• Track latest Redis integration component (Credis project).

Read the rest of this update entry...

 

[rdn]

Thanks for the update Xon

 

[maxicep]

Updated, we are following your updates carefully, because of better cache

Thanks.

 

[rdn]

Installed on 15M post large Forum I migrated from VB4

 

[Xon]

@RoldanLT wow.

23mb/s is easily the highest output I've seen before. You might need to-do tuning for how frequently it saves (or if it saves at all) the Redis DB depending on the host.

Peak Time Server Load:

5,200K+ Visitors now Guest/Members.

PHP 7.0.1
MariaDB 10.1.10
Nginx 1.9.9 (Still no fastcgi_cache implementation yet)
Redis 3.0.6

Awesome combi

Do you mean having "appendonly yes" ?

Can someone share all the settings to put into xenForo config.php please?

// Cache
$config['cache']['enabled'] = true;
$config['cache']['cacheSessions'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions'] = array(
'caching' => true,
'cache_id_prefix' => 'phc_',
'automatic_serialization' => false,
'lifetime' => 0
);

$config['cache']['backend'] = 'Redis';
$config['cache']['backendOptions'] = array(
'server' => '127.0.0.1',
'port' => 6379,
'use_lua' => true,
);

require(XenForo_Application::getConfigDir().'/SV/RedisCache/Installer.php');
// End Cache

SB only does between 6mb/s to 12mb/s or so.

Do you mean having "appendonly yes" ?

Yeah. Or disabling any saving.

Which I do on SB, since the 2GB linode which hosts the database and redis sometimes has latency issues that Redis is sensitive too. Might need to upgrade it to a 4GB linode sometime within the next 6 months.

Per the FAQ, something like:

$config['cache']['backend'] = 'Redis';
$config['cache']['backendOptions'] = array(
'server' => '127.0.0.1',
'port' => 6379,
'connect_retries' => 2,
'use_lua' => true
);
require(XenForo_Application::getConfigDir().'/SV/RedisCache/Installer.php');

Change server to the hostname or IP of the actual Redis instance.

 

[Mike Edge]

Oh so same as memcache, just different port Thanks @RoldanLT

 

[rdn]

Yeah. Or disabling any saving.

So from this page: http://redis.io/topics/persistence
Looks like having "appendonly no" has better performance than having "appendonly yes".

Where do I see this? Can't find it. I installed Redis, PECL and @Xon addon.

It should be on the admincp homepage, on the right hand column above the list of add-ons. You might need to scroll down some.
