 * Hi,
    Is there an option for the amount of memory that wp redis plugin should 
   use? because we have set to redis backend the maxmemory=10GB and the bytes metrics
   from wp is always under 5MB and the pages regularly full reload from database!

 * Hi [@marinblu](https://wordpress.org/support/users/marinblu/),
 * it could be that one of your plugins is constantly flushing the object cache.
   We have some notes on this here:

 * also, is the php redis extension necessary or only for the pro version?

 * The free plugin doesn’t require PhpRedis.
 * There is a comparison table on this page:

 * There is not a redis-cache-flush.log file after many hours, so I suppose that
   none of the plugins is flushing the object cache!
    Why the metric bytes form/
   chart it is always under 5000kb when I have set in backend the maxmemory to 10GB?
