I've noticed that my site motovlog.com has started to get a bit sluggish at times. The one thing that I haven't done yet is caching. Is it really as simple as adding some lines from this? https://xenforo.com/help/cache/ $config['cache']['enabled'] = true; $config['cache']['frontend'] = 'Core'; $config['cache']['frontendOptions']['cache_id_prefix'] = 'xf_'; How often does the cache reset etc? I don't want people to post then have to wait ages for it to show up?
