mChat server load

[NAPWR]

Hello Kasimi and all,

I have just moved our forum to a faster host,

and they now have told me that mChat is using a lot of resources,

which they also say, that too many more users using the chat will spill over the resources.


so the question here is:-

how can I reduce the mChat server load without turning it off ?

Make the refresh longer also maybe update to latest version ? my server stats droped with new version.

Hi NAPWR,

it all depends on how many users are actively chatting at the same time. Lately I get the feeling that hosts are quick to warn their customers about high resource usage even though it's not as dramatic as they make it sound.

One easy improvement you can make is to fix this bug in core phpBB which will be available in 3.2.4: https://github.com/phpbb/phpbb/pull/5157 The code change saves an UPDATE query on each add, edit & delete action in mChat.

For details about which of mChat's ACP settings affect performance the most, read here: https://www.phpbb.com/customise/db/exte ... pic/174966

thanks Terry2 and Kasimi,

is a bit out of my league with code changes.

That's easy: open the PR link I posted and click on the Files changed tab. Open your phpbb/sessions.php file. Now add all green lines to your file and delete all red lines. Maybe this side-by-side view helps too: https://github.com/phpbb/phpbb/pull/515 ... diff=split

Also, if you're running phpBB 3.2.0 or 3.2.1, use PHP 7.1. If you're running phpBB 3.2.2, use PHP 7.2.
