The most frequent reasons for slow operation are:

1. custom poorly optimized components that have logical errors;
2. components that perform complex and massive data fetch;
3. incorrect configuration of server software;
4. insufficient server resources for heavy traffic;
5. heavy site pages that are slowly transferred to browsers on sluggish transmission channels.

For even better performance, the usage of cache is highly recommended:

Also, you can use the compression module if you have it.
If not, use the Apache “mod_deflate” module.
This will allow to compress a page before sending it to a site visitor. The less is the size of the page, the faster it is transferred.

If you use custom components, optimize them; use cashing:

Proper configuration of the server software is also important.
If you have access to the server configuration, you can change it. Consult the web server configuration documentation.

If a page has the following content:

< ? require($_SERVER[“DOCUMENT_ROOT”].”/bitrix/header.php”); require($_SERVER[“DOCUMENT_ROOT”].”/bitrix/footer.php”); ?>

and also underperforms, the site template or the system part is the reason.

Check your site template for the inclusion of resource consuming components or code; for resource consuming agents with short run period (e.g. minutely RSS export); for event handlers that perform resource consuming operations.The most frequent reasons for slow operation are:
