cBB Blockgets Eating Too Much Resources

Postby Leinad4Mind » Tue Feb 05, 2019 3:56 pm • via Web
Hi there, I saw today that this extension is literally eating too much ram resources.

"Peak Memory Usage: 16.95 MiB" - This is per user. So if I've 50 users it will eat 847,5Mb of Ram. Thats too much :?

I have no solution to your problem, but I'm interested - how do you measure that?

In config.php I've uncomment this line:
// @define('PHPBB_DISPLAY_LOAD_TIME', true);

It's strange.
I need the name of the blocks installed in the page that causes this. (Screen capture is valid)

Honestly I've deleted all blocks that were disabled but on the acp, one at a time, and nothing changed.
Then I've disabled all active ones one by one, Disabled one, checked, nothing changed, I enabled it again, and did that for all blocks, to check if the culprit was any of it, but nothing... very very strange!
I can take a print if you want, but like I said, I didnt find the block that was the culprit of this :/
And I get the same values even as Guest.

Oh and I've some other pages as Calendar or Topic Index ( Where I only have the calendar or only the topic index) and they both uses 13~15Mb

EDIT: I've disabled all blocks and it goed from 16~17 to 13~14Mb Still a lot for a page without information

phpBB 3.2 without extensions or users, by default have a peak about 10Mb so, 13~14 is normal.
It is not nominal memory, it is the maximum memory peak per script.

The other day I did not read your message well. If the peak that marks you is about 16Mb, it is a correct value.
Multiply the number of users by the memory that marks you there is not correct, it is not a real value.

But in any other page as Index, viewforum, viewtopic, its always below 3Mb, why the portal is way bigger? Doesnt make sense.

And I enabled the phpbb time at config because my database is using 1Gb of Ram, and I am trying to figure out why, since with xenforo for example it would use 50mb for the same type of forum with the same users, posts etc. Can't beleive thats phpbb consume that much. :?

Only 3Mb. it seems too little

this value is php peak memory, no mysql memory.

I put you two captures. The first one is from the development forum (in this hosting) (only two extensions are installed, cBB Editor and Lightbox).
The second is from a forum on a private server (it does not have extensions)
Both are practically empty and are version 3.2.5

I see. Thanks for checking out and enlighten me.

It's what I get :lol:

I saw that phpBB made some changes, it was memory_usage back then, and it eventually changed to peak_memory_usage on the debug message.

I've read some topics about this at area51: https://area51.phpbb.com/phpBB/viewtopi ... 20#p276611 and http://area51.phpbb.com/phpBB/viewtopic ... 57#p251247
It was quite explainatory, and interesting to see the differences between 3.0, 3.1 and 3.2 too.
