The following memcached servers are not responding or not running

Hello @iamwpuser

Thank you for reaching out and I am happy to assist you with this.
If you have selected Memcached as a caching method for any caching module like Page Caching or Object Caching in the W3TC General settings page, The message you’re getting from the W3TC means that the W3TC can detect the Memcached extension, however, the Memcached service needs to be restarted or your apache/nginx.
W3TC only recognizes the PHP extensions, so make sure that the Memcachedphp extension is installed.
Check the service at the CLI/SSH: memcached-tool 127.0.0.1:11211 display and memcached-tool 127.0.0.1:11211 stats.
telnet 127.0.0.1 11211
should communicate with memcache and respond to status commands etc
Look if the service is running: ps afux | grep memc
restart the service if needed (as root/sudo): service memcached restart.

I hope this helps!
Thanks!

ok, thank you

I have some difficalties with memcached, and I don’t know what to do with this

I have cpanel with 4gb ram and 2 cpus, and they can do nothing with my memcached ??

Hello @iamwpuser

Thank you for your feedback.
Unfortunately, those are hosting limitations, or to be exact, shared hosting limitations.
The only thing that should be restarted is a Memcached service and not the hosting server.
I would recommend either upgrading the hosting plan or use Disk-based caching.

Thanks!

ok, it seems I can use only page cache with your plugin, because database cache, object cache and minify slowing down my website

but test says another things

so your powerful wordpress plugin and the most expensive hosting in the world totally can gives 20% to mobile page speed for wordpress site

you have to rename your plugin with name “slow your site” because only page cache is working in it, many other users dont have such expansive hosting like me, very interesting what are they can do with your plugin, who is bad you or my hosting for 30$ per month, or both

hosting support says to disable plugins and check perfomance when I have error with memcached in your plugin, and you telling me to upgrade hosting plan, so 4gb ram and 2cpus is not enough for your plugin? what does upgrade have to do with memcached error?

I am shocked from both of you

Hello @iamwpuser

Thank you for your feedback and I am sorry for any inconvenience.
A couple of points. I understand that some things may be frustrating. What shocked me most is the shared server costs $30/month.
Shared hosting is an arrangement in which multiple websites are hosted on one server. Resources such as disk space, CPU, and memory are shared, and costs are split between all the users on that server. So 4Gb ram and 2cpus are shared with every website that is hosted on that server.
I would appreciate it if you could share the hosting plan you are using or the link to that hosting plan as this. This is the reason why the hosting support told you that the server cannot be restarted, and this is because multiple websites are likely using the resources.

The optimal W3 Total Cache configuration takes into account a number of factors: your theme, your plugins, and the technologies available on the server. Since everyone’s site and traffic and theme are different, there is no one size fits all solution.

You should also take into account the idiosyncrasies of Web Performance Optimization (WPO) in a WordPress context. It means that WPO best practices have to be modified for WordPress because of how the application operates. The number of counter-intuitive realities could fill a small book.

Let’s go back to the Memcached problem. W3 Total Cache detects if the PHP Memcached module is installed on your server. The message you’re getting from the W3TC means that the W3TC can detect the Memcached extension, however, the Memcached service is not running. This means that if you select Memcached as a caching method, it will have no effect.

Regarding the score, you are getting 77/98 is actually a great score. Every website is built for the Desktop primarily. This means that the number of JS and CSS files that are used for the Desktop version is still loading on the Mobile version of your website, even tho the website is mobile responsive, which only means that it will show properly for mobile users.
For example, a single external file that is loading on your website, let’s say its font file called from google my some theme or a plugin, cannot be optimized by any plugin as the font is not coming from your server. And when it comes to mobile/desktop score, that same render-blocking file will reduce the mobile score by 30% more for mobile than the Desktop.

I am more than happy to assist you with any questions you may have, and once again I am sorry for any problems you may be having with the configuration.
If convenient, please share your website URL, as I would be interested in seeing the test results.

Let me know if you have any questions.

Thanks!

I don’t have any idea how to start run Memcached service
