# Persistent object caching

 * My site health pages says PERSISTENT OBJECT CACHING NOT ENABLED
 * The AMP plugin performs at its best when persistent object cache is enabled. 
   Object caching is used to more effectively store image dimensions and parsed 
   CSS.
 * Is it the Object cache option in w3tc plugin? If yes, my hosting people recommends
   not to enable it. Can you clarify?
    Thanks

 * Yes, W3 Total Cache has object caching. If your host doesn’t recommend using 
   W3TC for object caching, do they have another recommendation?

 * Object caching is a best practice for improving WordPress site performance generally,
   and it’s especially beneficial with AMP.

 * “The object caching does not work well with our servers and is likely to cause
   issues. I would suggest to avoid it as much as possible.” this is the response
   
   They said “try to activate object cache on w3tc and see if there are any problems–
   if there are any deactivate. No one of the options provided in the page you refered
   Does w3tc object cache work the same ?

 * I’m guessing your server doesn’t have a persistent object caching service, like
   Redis or Memcached. So that’s why your host doesn’t recommend it.
 * W3TC has alternative object caching backends which you can use.
 * Nevertheless, object caching is not required. It’s simply recommended. The most
   important thing is to have page caching, which apparently you do have with W3TC.
   So you can ignore the object caching recommendation.

 * This is very helpful. I’ll contact InMotion Hosting and see if they do Redis…
   W3 was too complicated for me, though I stuck with it for years.

 * I’m so grateful to you Mr. Ruter!!! I called up InMotion Hosting and they now
   have hosting specific to WP. My old hosting didn’t support persistent object 
   caching, just as you had mentioned. So I switched to the WP hosting plan… which
   I would not have known to do without your help.
 * Thank you, Thank you!!!!
