Question Replying to a post much slower than creating a post

I backed up my live site today and restored it on xampp on my local machine. Replying to posts using my local copy has no time delay at all while it is about 10 seconds on my live site.

I am looking for differences between the live site and localhost. My host has PHP 7.0.10 while the localhost is 7.0.13.

Are there are areas that I can look at to solve the issue please?

like php mod-security or something like that, or cache improvements.

Did you ever find a solution? We have the same problem here.

I made a post a month ago with the same problem. I can't find a solution either. I have disabled everything as well. It's weird that the edit and posting is fast and only the reply is slow.

No. I am still searching for a solution. I thought it was perhaps an old module but the fact that the issue does not occur when I run a copy locally suggests this is not the case. I did try all the cache permutations on my live, hosted site with no improvement.

I have noticed that editing and saving an existing post is instantaneous. My issue happens every time I reply to a new thread or a post within that thread.

Joomla and Kunena are up to date.

Last week I upgraded Kunena to 5.0.7 and, for the first 10 replies, the upload had no time delay. However, after only a short time, the delay in posting a reply returned. Creating a new post continues to have no time delay.

What was it in upgrading to the latest version that temporarily resolved the problem?
