XF 1.2 [LF Recommendations] MemcacheD BackEnd Other Cache Options?


Active member
Hey All,

I am looking to see if there are any other good options/recommendations for things I should Cache using my BackEnd MemCacheD System.

Here is my current config:
$config['cache']['enabled'] = true;
$config['cache']['cacheSessions'] = true;
$config['cache']['backend'] = 'Memcached';
$config['cache']['backendOptions'] = array(
    'compression' => false,
    'servers' => array(
            // your memcached server IP address X's for Privacy
            'host' => 'xxxxxxxxxxxxxx',
            // memcached port
            'port' => 11211,
You can see I am currently caching sessions. I tried looking at the Zend documentation that I was linked to via Xenforo.com/help/cache/ but I am afraid it was a bit confusing! Are there any other optimizations I should consider? I already have FastCGI caching on via NGINX and I have integrated a CDN via these options:
$config['externalDataUrl'] = 'http://cdn.xxxxx.com/data';
$config['javaScriptUrl'] = 'http://cdn.xxxxx.com/js';
And I have aslo enabled Gzip via Config.php & NGINX

Thanks for any advice :)
ngx_pagespeed can use memcached to cache some things but just used it for 3 days and increase my site with +1second in load with some high cpu load for nginx, I don't recommand to use ngx_pagespeed with xenforo.
What config do you used for FastCGI caching ? Just tried to make it working and failed, can you share it with us ?

Just below this area:

http {
    include      /etc/nginx/mime.types;
    default_type  application/octet-stream;
I placed This:
    fastcgi_cache_path  /{DIRECTORY FOR CACHE}  levels=1:2
                      keys_zone={NAME FOR CACHE}:128m
    fastcgi_cache_key "$scheme$request_method$host$request_uri";
AND in the Server configurations starting with:
server {
        listen      80;
I put this for the PHP:
location ~ \.php$ {
            fastcgi_pass  {Usually an IP:PORT OR Unix Socket. I Use a Backend UpStream using Multiple PHP Rendering Systems};
            fastcgi_index index.php;
            fastcgi_cache  {NAME FOR CACHE};
            fastcgi_cache_valid  200 302  30m;
            fastcgi_cache_valid  301      1d;
            fastcgi_cache_valid  any      15m;
            fastcgi_cache_min_uses  1;
            fastcgi_cache_use_stale error  timeout invalid_header http_500;
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include /etc/nginx/fastcgi.conf;
I have been slow increasing the cache time to see what is most optimal.. The time you see is just were I am at the moment.. So far people can still post and see the instant results so no interference there.

I also have GZIP enabled on both NGINX & Xenforo.

To date my Cache has only amounted to about 11MB but these are not really high traffic sites. I will be planning on moving a big site soon and will let you know how that goes :)

                        fastcgi_param PATH_INFO $fastcgi_script_name;
                        fastcgi_intercept_errors on;
To store full page in memcache, but i think there need to use some cookie.
