Why Forum index page is loading harder?

[gaby]

Hello,

I just upgraded my 3.4 to 4.0.7 and it seems to be fine and nice, but i have a problem. The whole forum is loading a little bit harder than the previous version, and the index page is loading hardest than topics or forums.
Here, on invisionpower the index page and the whole forum is loading faster than mine. I can do something to improve the load speed?

Thank you!

By harder do you mean slower?

Some people have noticed problems with the forum index which were cause by certain sidebar widgets. You could try to deactivate them and see if it helps.

​Yes, slower is the right word.

Do you have gravatar enabled? It slows down the site significantly due to redirects.

 

Do you have external js or css files? Check if the servers serving them is slow.

 

Do you have an expires header on? If not, do so please.

 

Is caching on your forum available? I recommend using memcached..

 

Do you have any plugins using excessive CPU? You can check so by loading the site while htop is on (linux machine) and check if MySQL/Apache/Nginx/MariaDB/PecoraDB/PostgreSQL is using too much CPU.

I don't have gravatar enabled.

Expires header? Can you tell me how to do that?

i assume you use apache:

 

http://httpd.apache.org/docs/2.2/mod/mod_expires.html

 

on ubuntu i would do it like this:

 

sudo a2enmod expires

and then put in the following lines in my .htaccess in the root directory of my forum:

 

<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 1 month 1 days"
ExpiresByType text/html "access plus 1 month 1 days"
ExpiresByType image/gif "access plus 1 month 1 days"
ExpiresByType image/jpeg "access plus 1 month 1 days"
ExpiresByType image/png "access plus 1 month 1 days"
ExpiresByType text/css "access plus 1 month 1 days"
ExpiresByType text/javascript "access plus 1 month 1 week"
ExpiresByType application/x-javascript "access plus 1 month 1 days"
ExpiresByType text/xml "access plus 1 seconds"
</IfModule>

If the forum in question is the same as the one in your signature, I tested it and:

1st load: 7.95 seconds

2nd & 3rd load: 2 - 3 seconds.

Your Page Size is also big. Too many images on board index.

Well I find that the forum I run is slow, and it's only been slow since 4.0.7. Ironically, when I load the forum in Internet Explorer, it loads instantly, but in FireFox or Chrome, it is noticeably slower.

IE ftw!

I don't know if this helps but..
