Robin! You lead me down the path to find the problem!

It turns out it was the enormous amount of forums/categories underneath one category. When I broke the 365 forum categories into groups of 50, the speed improved.

Here’s what I found:

Every 20 forum categories within another forum category adds another second to the posting time. So 365 lesson categories within a single category called lessons = 18 seconds for a post to save and appear. When I broke the 365 lesson categories into 7 categories (“lessons 1-50” and so on…) I got the posting speed down to 2.5 seconds.

1. Is there a known issue with bbpress slowing down where there are a large number of “category” forums within another category? Now we know that that’s what my problem was.

2. Since we’re a new site with no posts yet, I have faith that a large number of posts and replys won’t slow down the forums like the issue defined and resolved above. Care to reassure me on this? 🙂

Thank you so much for your help!!

In addition to above, I just updated from 2.5.8 to bbpress 2.6, the problem remains.

Another note, I noticed when I submit a new topic or reply and wait the 17-20 second, if I hit refresh after 3 seconds it’s already there submitted and waiting on the page… it’s like behind the scenes it is working fast but there’s some delay for the browser to be told to go ahead and refresh to show the update. Maybe this info helps…

I ran the repairs and the problem still remains.

This is perplexing. When I compare the slow forums to the not slow forums I don’t see a difference. Both are under multiple “category” forums… (I was originally thinking maybe it’s slow because it’s two categories deep… but the faster forums are too.)

Slow:
HOME / FORUMS / ACIM LESSONS / LESSON 1 / LESSON 1 – INSIGHTS

Fast:
HOME / FORUMS / ACIM TEXT / PREFACE & INTRODUCTION / PREFACE & INTRODUCTION – INSIGHTS

————-

I was wondering if it’s a database issue? I looked to see if we had similarly titled pages that could be confusing WordPress. We do have similar pages:

Slow Forum:
HOME / FORUMS / ACIM LESSONS / LESSON 1 / LESSON 1 – INSIGHTS

WordPress page:
HOME / ACIM LESSONS / LESSON 1 /

— So, I changed those to the following:

Slow Forum:
HOME / FORUMS / ACIM LESSONS / LESSON 1 FORUM / LESSON 1 – INSIGHTS

WordPress page:
HOME / ACIM LESSON INDEX / LESSON 1 /

After changing I deleted old revisions and optimized database. The slow forums remained slow.

————-

You could just say to try to delete and recreate the slow ones… but there’s 365 top level category forums and each category has two categories within for a total of 1,095 forums to recreate.

(Before I get beat up on that, these are forums for a lesson book with 365 lessons and we wanted two categories within each lesson (sharing and Q&A))

Thank you for continuing to help me figure this out!
