I’m not sure where you’re getting those stats, but I doubt that is showing you the amount of memory being used while processing the images. If you navigate to some memory use screen, you’re seeing the amount of memory currently allocated, which is now an entirely different process from when you were uploading images. The … Read more
Try one (or more) of the below methods to increase the memory allicated by PHP. First try increasing the limit to 64MB, and if that fails use 96M. You can define the WP_MEMORY_LIMIT constant in wp-config.php: Increase PHP Memory to 64MB define(‘WP_MEMORY_LIMIT’, ’64M’); Increase PHP Memory to 96MB define(‘WP_MEMORY_LIMIT’, ’96M’); You can also change the … Read more
Using FTP, try increasing the memory for PHP and WordPress by editing the memory_limit line in your php.ini (if you have access to it) to 64M or 128M, which should be fine for non-multisite installs. memory_limit = 64M; If you can’t get to the php.ini file, add this line at the top of your .htaccess … Read more
In your example, you are getting all the fields in the get_users call, but you are only really using the ID and display_name fields. So you can save some memory by forcing get_users to only get the fields you need. $users = get_users(array( ‘role’=>’s2member_level3’, ‘fields’=>array(‘ID’, ‘display_name’), )); That will help reduce your memory footprint.
Excessive memory used by update_option()
I think I found what the problem was. WP-Postviews. I deactivated the plugin and removed all code from it on the site and now everything is running smoothly (at least for the last 3 hours).
wp-config.php sets the memory limit for the specific WordPress site which has that file. php.ini will effect your whole server. The php.ini is the parent setting, and so you can set WP to whatever you want within php.ini‘s range. It’s also importan to note there is a WP_MAX_MEMORY_LIMIT where you can define a max amount … Read more
Rewrite to and this will use much less memory. Whereas p = p*alpha allocates a whole new matrix for the result of p*alpha and then discards the old p; p*= alpha does the same thing in place. In general, with big matrices, try to use op= assignment.
A byte is a memory unit for storage A memory chip is full of such bytes. Memory units are addressable. That is the only way we can use memory. In reality, memory is only byte addressable. It means: A binary address always points to a single byte only. A word is just a group of bytes – 2, 4, 8 depending upon the data bus size of the CPU. To understand the memory operation fully, you must be familiar with the various registers of the CPU and the memory ports of the RAM. I assume … Read more
This one here: seems to be very inefficient and expensive for large strings. Better do A buffer object keeps a reference to the original string and start and length attributes. This way, no unnecessary duplication of data occurs. A string of length l has l*l/2 sub strings of average length l/2, so the memory consumption would roughly be l*l*l/4. With a … Read more
