Hello @swinggraphics,
the issue is generally caused by some dynamically generated CSS/JS files that are forcing the re-generation of the CSS/JS combination file on every request. When this happens, the culprit should be identified and excluded from the CSS/JS combination functionality in our plugin. The following filters can be used as well:
add_filter( 'sgo_css_combine_exclude', 'css_combine_exclude' );
function css_combine_exclude( $exclude_list ) {
// Add the style handle to exclude list.
$exclude_list[] = 'style-handle';
$exclude_list[] = 'style-handle-2';
return $exclude_list;
}add_filter( 'sgo_javascript_combine_exclude', 'js_combine_exclude' );
function js_combine_exclude( $exclude_list ) {
$exclude_list[] = 'script-handle';
$exclude_list[] = 'script-handle-2';
return $exclude_list;
}More information regarding the custom filters can be found here:

Also, there is a cron event that should clear the siteground-optimizer-assets folder once a day if exceeds 1000MB. The cron event is called
siteground_optimizer_check_assets_dir
so you can check if this event is scheduled correctly.
If none of the above works for you and your site is hosted at SiteGround, you can open a support ticket and our support team will help you identifying the cause of the issue.
