CPU spike when opening multiple tabs

  • I randomly noticed that if I quickly open my site in multiple tabs in my browser, it causes the CPU on my server to spike to 100% and the site gets overloaded. Is this really normal? I tried my competitors sites, and I don’t notice this phenomenon.

    Regards

    Generating page needs some CPU power and system resources, also serving static assets need some (however its much less than constructing a page with PHP).

    You can do some caching in order to reduce that load spike, there are many hints and recipes for WordPress optimization as well as system optimization (i.e. MySQL throughput)

    Hi, thank you for your response. I do use caching. I use WP Rocket cache as well as Cloudflare. I used some elastic scaling with my host and added a few CPU cores, and this helped it from spiking to 100%, but quickly opening many tabs still affects the CPU load. Is this normal and expected?
