The object cache system uses just one file, which means that it is simple to set up:
Download the file from .
Rename the file to
object-cache.php
and upload it to your/wp-content
folder. Note that this is not a plugin, so it doesn't need to go in theplugins
folder.The cache should start working immediately. View a post on your site and then check
/wp-content/cache
.If there's nothing in that folder, check the file permissions. Setting them to 755 via your FTP client (or using
chmod
if you prefer to use the shell) should be sufficient for most server setups.Once files start appearing in the
/wp-content/cache
folder, you can be confident the cache is working.
Donncha's object cache isn't exactly flashy, but it gets the job done. The cache is still experimental, but in the testing I've done, I have found that it works well. Donncha offers some more information about the cache on his site
