Hi,

I am nearing completion of development for a client using the Woopress theme, and I have noticed a performance issue when displaying related products on a single product page.

I have narrowed it down to the etheme_create_slider function in theme-functions.php and more specifically, the following while loop:

while ($multislides->have_posts()) : $multislides->the_post();
$_i++;

if(class_exists(‘Woocommerce’)) {
global $product;
if (!$product->is_visible()) continue;
echo ‘<div class=”slide-item product-slide ‘.$slider_type.’-slide”>’;
woocommerce_get_template_part( ‘content’, ‘product-slider’ );
echo ‘</div><!– slide-item –>’;
}

endwhile;

I have put some timing debugging code at the beginning and of the function – and its taking 8 seconds in some cases to execute the function – see private content for live example.

Many thanks

Please, contact administrator

Hi,

There appears to be a problem with the theme when viewing a product- the related products section is taking a very long time (e.g. approx 8 seconds) to be displayed.

If you view the link I supplied in the private section, you will see this behaviour. I have also echo’d time-stamps before and after the code that generates the related products to demonstrate that its that code causing the problem and the time it is taking.

Many thanks

Hi,

I’m not sure you understand. Its not the general wordpress site performance – its a specific a piece of code in the woopress theme.

When I disable ‘display related products’ in the theme options, the site’s performance is fine. When I enable that feature its takes about 8 seconds for that code to generate and display the related products – that shouldn’t be the case.

Please advise.
Thanks

Hi,

I have managed to alleviate the problem by reducing the number of items that it attempts to display in the slider by adding the following filter function:

add_filter (‘woocommerce_related_products_args’, ‘rev_related_products_args’,1);
function rev_related_products_args ($args) {
$args[‘posts_per_page’] = 8;
return $args;
}

Without it, it defaults the posts_per_page to (in my case) 50 – which results in terrible performance as it creates the slider.
