WordPress tells us: the WP_MEMORY_LIMIT option allows you to specify the maximum amount of memory that can be consumed by PHP. This setting may be necessary in the event you receive a message such as “Allowed memory size of xxxxxx bytes exhausted”. Or as the PHP docs put it [A memory limit] helps prevent poorly … Read more
I have checked your code, and I think you are missing the guid of the images. Please have a look at the code below: $post_id = 1234; $images = array(‘filename1.png’, ‘filename2.png’, … ‘filename10.png’); // Get the path to the upload directory. $wp_upload_dir = wp_upload_dir(); foreach($images as $name) { $attachment = array( ‘guid’=> $wp_upload_dir[‘url’] . “https://wordpress.stackexchange.com/” … Read more
You can try a trick with querying post data directly and setting filter field of post objects to sample before passing it to get_permalink() to reduce memory usage. See get_permalink memory usage issue for detailed reasoning behind it.
Theoretically, editing your config.php and add this line before wp-settings.php inclusion. define(‘WP_MEMORY_LIMIT’, ‘256M’); should raise your memory limit for WordPress to 256MB or whatever value you set. And this will work sitewide. However, as sorich87 pointed out, there are few functions that will alter this setting with hard coded 256 MB limit. To Hack or … Read more
Excellent responses on WP Hackers: http://lists.automattic.com/pipermail/wp-hackers/2012-June/043213.html What you’re doing with that query, is loading EVERY matching post into memory, including the full post contents. As you can imagine, this is probably quite a lot of items. You can pass ‘fields’ => ‘ids’ into WP_Query to simply return a list of matching post_ids instead, which should … Read more
The problem comes from the fact that, in order to display pages and their hierarchy, WP has to load all of them and then build the tree in memory. So, you are saved if you can convert most of those pages into one or several non-hierarchical custom post types. The permalink structure can be emulated.
Not worth the trouble. WordPress doesn’t eat a lot of memory just-because. It eats a lot of memory because it runs a lot of functionality under the hood. It is far more easier and efficient to cache results (page generated) with static cache plugin and serve that. That way most visitor will not even hit … Read more
malloc(sizeof(int)) means you are allocating space off the heap to store an int. You are reserving as many bytes as an int requires. This returns a value you should cast to int *. (A pointer to an int.) As some have noted, typical practice in C is to let implicit casting take care of this. malloc(sizeof(int*)) means you are allocating space off the heap … Read more
Byte: Today, a byte is almost always 8 bit. However, that wasn’t always the case and there’s no “standard” or something that dictates this. Since 8 bits is a convenient number to work with it became the de facto standard. Word: The natural size with which a processor is handling data (the register size). The most common word sizes … Read more
hive.tez.container.size This property specifies tez container size. Usually value of this property should be the same as or a small multiple (1 or 2 times that) of YARN container size yarn.scheduler.minimum-allocation-mb and should not exceed value of yarn.scheduler.maximum-allocation-mb. As a general rule don’t put value higher than memory per processor as you want 1 processor per container and … Read more
