Xcache + Memcached

[Zhana]

Hi,

Is it possible to use both xcache and memcached? Would it increase any performance?


Thank you.

Yes you can use both; Xcache is a PHP Opcode cacher and memcached is a data cacher - they do different things, but both should help increase performance if configured correctly.

Cheers,
Shaun :D

IfAs cycled said yes if configured right, If not then you will see high memory usuage and the /tmp may fill up rather fast.

Thx Gary, I guess I'll hire you again :P


Will I be able to edit the config like this?

$INFO['use_xcache'] = '1';
$INFO['use_memcached'] = '1';


Thank you.

$INFO['use_xcache'] = '1';

$INFO['use_memcached'] = '1';

Thank you.

Thank you.

You can only set one cache in conf_global.php, but you can set IPB to use memcached there and still use a different opcode cache without doing anything at all to configure it onther than setting up the php config file.

Using debian, i have /etc/php5/conf.d/apc.ini containing the following:


extension=apc.so
apc.enabled=1
apc.shm_segments=1
apc.shm_size=128
apc.ttl=7200
apc.user_ttl=7200
apc.num_files_hint=1024
apc.mmap_file_mask=/tmp/apc.XXXXXX

conf_global.php contains the following extra lines:


$INFO['use_memcache'] = 1;
$INFO['memcache_server_1'] = "127.0.0.1";
$INFO['memcache_port_1'] = "11211";

Note that you have to include the last two lines for it to work. If you're not using a distributed database setup (which I might be moving to soon) the above defaults should work.

Thanks Elvis. BTW can you please tell how much RAM your system has?


Thank you.
