Website uses (too) much Physical Memory: how to figure out cause

  • Hello, regularly we get the message “The connection waiting time has expired”. This happens in the backend but also frontend. Also, last week I got three days 1 notification from Uptime Robot that the site was unreachable (lasted <2 minutes). At times when there are no/barely any visitors and and no one is administering.

    Perhaps there are different causes for these two problems. From the administrator, I understand that at the three times last week, (too) much Physical Memory is being requested and errors occur as a result. I see this reflected in the graphs they sent me at the same times. According to hosting party, there are then processes running in the background. I know that Updraft’s automatic backup process was not running at those times. I can’t get access to DirectAdmin. I do get access to phpAdmin.

    Question 1: How can I find out which process(es) are taking up so much memory in the background?

    For the page loading problem, I want to do the following: thin out some plugins, use WP-Sweep once and maybe start using WP Super Cache. Although I don’t notice any difference with the latter on a test website yet.

    Question 2: Are there any other options?

    Thanks for thinking with me!

  • I would recommend deactivating plugins on a test basis. Especially those that add major features to your project. Does the loading time change after deactivating them? If so, then you have found the culprit plugin (after several attempts).

    Using an optimization plugin like Super Cache for this is not a real solution – it only masks the effects.

    Maybe the resources provided by your hoster are too low. Talk to their support about it.

    Thank you I will try that. So I understand that a plugin can also has a performance impact even when I am working on the backend. E.g. refreshing the users list?

    I did email with the support desk. The max physical memory is 1 Gb.

    Yes, a plugin can also have an unfavorable effect in terms of form. There are many ways in which this could happen. By disabling it, you exclude it as a cause.
