Search page is very slow with more 400 products

Hi, the search is very slow when the products to look for are more than 400 or so. The ajax search on the other hand is very fast. At the moment I am forced to use a second plugin for the search page which is very fast and use yours only for the ajax search. I have already made all the changes that you have recommended to other users such as not including the variants, removing all the fields and taxonomies that I do not want from the index, limiting the results per page but in any case if the search exceeds 350/400 results it also takes dozens seconds to charge.
I would also like to use your plugin for the search page because I prefer it for functionality and it has compatibility with berocket ajax filter but at the moment it is impossible for me
These are all the functions enabled:

function aws_page_results( $num ) {
return 350; // number added so as not to make the search very slow but in doing so it does not show all the results but always limits to 350
}

add_filter(‘aws_posts_per_page’,’aws_posts_per_page’);
function aws_posts_per_page( $num ) {
return 48;
}

add_filter(‘aws_indexed_data’, ‘my_aws_indexed_data2’);
function my_aws_indexed_data2( $data ) {
if ( $data[‘type’] === ‘child’ ) {
return false;
}
return $data;
}

add_filter(‘aws_indexed_data’, ‘my_aws_indexed_data’);
function my_aws_indexed_data( $data ) {
$new_terms = array();
foreach ( $data[‘terms’] as $source => $all_terms ) {
if ( strpos( $source, ‘title’ ) === 0 || strpos( $source, ‘category’ ) === 0
|| strpos( $source, ‘attr_pa_fantasia’ ) === 0 || strpos( $source, ‘attr_pa_materiali’ ) === 0
|| strpos( $source, ‘attr_pa_taglia’ ) === 0 || strpos( $source, ‘attr_pa_altezza-vita’ ) === 0 || strpos( $source, ‘attr_pa_collezione’ ) === 0 || strpos( $source, ‘attr_pa_scollatura’ ) === 0
|| strpos( $source, ‘attr_pa_stile’ ) === 0 || strpos( $source, ‘attr_pa_stile-borsa’ ) === 0 || strpos( $source, ‘attr_pa_stile-capospalla’ ) === 0 || strpos( $source, ‘attr_pa_stile-gonna’ ) === 0
|| strpos( $source, ‘attr_pa_stile-pantaloni’ ) === 0 || strpos( $source, ‘attr_pa_stile-portafoglio’ ) === 0 || strpos( $source, ‘attr_pa_stile-tacco’ ) === 0 || strpos( $source, ‘attr_pa_stile-vestito’ ) === 0
|| strpos( $source, ‘attr_pa_stagione’ ) === 0 || strpos( $source, ‘attr_pa_stile-camicia-blusa’ ) === 0 || strpos( $source, ‘attr_pa_stile-coprispalle’ ) === 0
|| strpos( $source, ‘attr_pa_tipo-chiusura’ ) === 0 || strpos( $source, ‘attr_pa_tipo-costume-da-bagno’ ) === 0 ) {
$new_terms[$source] = $all_terms;
}
}
$data[‘terms’] = $new_terms;
return $data;
