WP uses Lots of RAM (Screenshots Attached)

So you deactivated all plugins and still got 13s median load time? The default WordPress install should load in around 300 ms. You can also install the Debug Bar plugin which will tell you exactly how much memory WordPress uses for a particular request, but 13s is way too high per request.

Don’t forget that themes can cause high load times and memory usage as much as plugins.

No the 13s Median Load time is Real User Monitoring with all the necessary plugins activated. Installed Debug bar what would you like from me as a screenshot?

WARNING: wp-content/themes/hottopix1/category.php:139 – in_array() expects at least 2 parameters, 1 given
require(‘wp-blog-header.php’), require_once(‘wp-includes/template-loader.php’), include(‘/themes/hottopix1/category.php’), in_array

In that case deactivate all the plugins and activate one by one to find out which one is causing the load time to skyrocket. Chances are that the same plugin is causing the high memory usage. From Debug Bar at the top you’ll be able to see the memory used to serve the current request.

The memory usage after disabling all the plugins is 22MB. When Activating 40MB

Yeah, that’s a fairly adequate memory usage, given that you’re not running an empty WordPress install.

All the plugins are quite necessary. Currently there are around 35 visitors on the website.

Do you think is time for an upgrade?

No. I have sites with > 100k pageviews per month merely using 15% of a 1CPU/1G box. As I said, your memory usage is fairly adequate, it probably is not the bottleneck for your slow load times. Try profiling a request with xdebug or xhprof to see what your plugins are doing for 13 seconds before serving a page.

On December we discovered some malware do you think that there is an issue there?

It could be, but it’s hard to tell exactly without reviewing and profiling your code. I can take a quick look if you like, you can email me at kovshenin at gmail dot com.

I have sent you an email.
