    and i have object
   cache pro in my server, and i am checking multiple times, and this metric is

 * Are you talking about “Redis object cache pro” plugin from Till Kruss?
 * Does Redis daemon run on the same server or on separate one?
 * I would like to say few words about this “object cache” benchmarks. In general
   I am not happy with it, as it is, as you say – show mixed results. If you try
   some really simple-disk-and-memory based plugin – you will be surprised, that
   it might give you higher score. But as programmer and system administrator – 
   for performance, reliability and scalability – I clearly would trust Redis much
   more. But from WordPress point of view (and from plugin point of view) – I can
   not detect or identify it. Plugin simply measures time for operations, that are
   common. So this “object cache” implementation is not purely hardware thing (similar
   to database performance, but a bit different). Object cache performance also 
   depends on PHP code of other plugin and caching mechanism used by it. And this
   gives us pretty wide range of different possible combinations “how it could be”.
   And if you ask me – it does not add trust into this score. So yes, I have mixed
   feelings about it myself. You could add to this discussion a fact, that not all
   people use object cache and if you disable object cache benchmark – your score
   will be better. :/

 * i am using Cloudways and they give Object Cache Pro in their servers.
 * i understand
    i do think object cache is important, and i am trying my best to
   compare different hosting with some tests including your plugin. but i have trouble
   getting higher score in this section, and i don’t know what i need to config 
   or change.
 * Thanks

 * for example take a look at these results from my dev-server
 * W3TotalCache with file-based object cache
    [https://report.wpbenchmark.io/U1aQEKJLmF/](https://report.wpbenchmark.io/U1aQEKJLmF/)
 * W3TotalCache with REDIS based object cache
    [https://report.wpbenchmark.io/9yVDlDLT3q/](https://report.wpbenchmark.io/9yVDlDLT3q/)
 * Docket-cache plugin for object cache
    [https://report.wpbenchmark.io/I82UGS0vzW/](https://report.wpbenchmark.io/I82UGS0vzW/)
 * in theory and logically – the redis-based object cache should be fastest, but
   if you ask me – they all 3 look pretty mixed without clear winner. If you ask
   me – any object caching, that works – is good and enough. It’s not the most important
   metric, that affects speed of your page.
 * My experience shows, that most of all users will need CPU and RAM memory performance,
   then MySQL performance, then filesystem (well, this affects MySQL as well, but
   CPU for heavy tasks is what people will notice most).
