For a few weeks, I get some extreme resource usage spikes every hour. I only host the website ImproveYourArchery.com (WordPress) and a LimeSurvey survey on this hosting. My website ImproveYourArchery.com is linked to Ezoic and Cloudflare.

I don't know why this is happening or what to do next. Could someone with a bit more technical knowledge help me?

Thanks in advance!

Hey there! It's hard for me to tell from the graphs what the timeframe is, but it seems to be happening regularly. Is there a cron on the account that does something, like a mailing list or an update of some sort?

In general, though, from these particular images, the usage doesn't look too extreme as it's never getting above 20% CPU or 50% RAM.

Thank you for your thoughts. I know that my CPU and RAM aren't that high, therefore I don't think it's caused by normal web traffic. But my I/O usage is what causes the errors. I Googled this issue again and some guides told me that I/O usage doesn't matter that much, while others said that it can cause a lot of issues.

I didn't configure any cron jobs myself, apart from one, which is set on 2 times per day (0,12 per hour). This was recommended in a tutorial from my host to speed up Wordpress. You can see all the cron jobs below:

Thanks for the additional details.

Is that the I/O of the disk itself? If so, it can definitely be a major issue, as even a small cron that is accessing the disk could cause a spike.

I'd recommend reaching out to the hosting provider to see if they can test the hard disk itself, as high I/O with little CPU or RAM activity can be an indicator of a failing drive.

Yes, I believe the I/O is of the disk itself. But I think I have to switch to another host. It took ages to get in contact with customer service and when I talked about this issue, they tried to upsell me to a higher package. But that doesn't make a lot of sense to me because the CPU and Physical memory stay at reasonable levels.

Thanks for your answers!
