Hello, 

I visited the link you sent and I am on the Table Engines section.

First of all the image in the link shows the database entries as

• wp_wpforo_forums
• wp_wpforo_posts
• wp_wpforo_topics
• wp_wpforo_profiles
• wp_wpforo_views

On my database these show as:

kqd_wpforo_forums

kqd_wpforo_topics

kqd_wpforo_views 

etc

Is that okay?

Secondly there are two database entries that are not present in your image or my table i.e. wp_wpforo_views and wp_wpforo_likes.

Is this an issue?

Anyways I just had to change one entry i.e. kqd_wpforo_visits to MyISAM while the rest were all as recommended. 

Also on the wpforo cache section, there are several options that you said need to be turned on such as

• Enable Member Cache
• Enable Object Cache
• Enable Memory Cache

However there is only one cache option in wpforo i.e. enable cache and that is already turned on.

All my forums and subforums are on simplified layout as you suggested and there is no loopback issue as well. I always had my community forum (wpforo) on my cache plugin's exclusions as well. I am not sure if making that MyISAM change will be enough to make a speed change.
