Hello everyone, I'm new here and signed in in order to ask a question concerning an issue our website is facing. In the last month we have experienced our site slowing down somewhat. Simultaneously, cPanel has reported an increase in resource usage and occasional peaks. If you look at the attached image, you will see that a noticeable change took place in the average and peak usage at the April 20th mark. That is also when we started experiencing sluggishness in the site's UX. We are using a Wordpress site with shared hosting. There were no major changes done to the site at that period, nor has there been unusual amount of traffic coming to our site. The only thing that we did do around that time or a week earlier was to turn off automatic redirecting of users to their country's language version (we are running a multilingual site), due to the fact that this feature had been causing issues regarding the findability of certain pages on Google. Other than that there haven't been any new plugins installed or other major additions done. Our hosting provider recommended an upgrade that we then made after a week of experiencing these issues. After the upgrade we have the following resource limits at our disposal: > 25% 4 vCPU > 8192M MEM virtual > 2048M MEM physical > 80 EP > 4096 kbps IO This upgrade did nothing to alleviate our issues however as we were and still are experiencing peak hits in our physical memory, entry processes as well as CPU. When asked about this, our provider recommended dedicated hosting and was reluctant to offer any other solutions. They then did tell me over the phone that I should check out if there are some plugins that are causing problems and also check the size of images. Our images had been optimized a month before with the help of a special plugin, and even before that was done the site was running ok, so I didn't suspect that to be the primary cause. What I then did was to update all the plugins, installed P3 Plugin Profiler and turned off some unnecessary ones. This did help somewhat in terms of site speed, even though some of main culprits identified by the plugin profiler were plugins that were necessary for running and updating the site smoothly, such as Sitepress Multilingual CMS and WPML String Translation as well as Advanced Custom Fields. Those things have been with us since the very beginning of our Wordpress site. But even as the site's speed had visibly improved, we still hit resource limits almost every day, and usually in the evening or at night. I then looked up what else could be causing these things. Somewhere I read that Wordpress sites frequently come under brute force attacks and checked the log of our security plugin, which I nor anyone else had admittedly paid any great attention to in the past. It showed that there had been multiple login attempts from suspicious sources every day, almost every hour during the last month (the log didn't extend beyond that, so I can't tell how it looked before April 20th, for instance). There had been no breach, however, and the IPs where the attempts came from were always locked out at and eventually banned. I then tightened the security measures so that a lockout would occur earlier and last longer and banning would take place earlier as well. So far the attacks have at least become less frequent, but those resource limits still keep getting hit (see the attached report from the last 24 hours), so that has made me wonder about the relationship between these two things or whether there is something more that could be done. Are there any other things that could be done, either something to improve upon the aforementioned measures or something else entirely?
