WordPress is a great way to get your online store up and running quickly and cheaply – but in the wrong conditions, it can run pretty slowly.
If it takes anything longer than a second or two to display pages, customers will turn away.
So what to do? Here are some suggestions that can help to speed things up.
Web Server
There’s not a lot you can do if your site is being served from an old laptop stashed in your IT guy’s cupboard at home (which, hopefully, it isn’t..)
Have a look at the hosting level you’re set up for – cheaper monthly fees will generally result in lower processing power and memory availability, which can be a false economy resulting in customers turning away because of slow page load times and lower Google rankings.
Memory Limit
In your wp-config.php file
define('WP_MEMORY_LIMIT', '128M');
In php.ini
memory_limit = 128M
Change the ‘128M’ part if you wish, but it should really be at least 96M or you can run into problems with some plugins not working at all.
