How can I troubleshoot disk usage by XWiki?

Hello, I’m having an issue with XWiki and I’d like to know how can I start troubleshooting the site in order to find the culprit - My challenge is this:

As you can see, my disk “reads” go through the roof and I am not quite sure why!

I was checking my catalina logs and I found these error messages:
Unable to add the resource at [/WEB-INF/classes/META-INF/services/org.xwiki.component.annotation.ComponentDependencyFactory] to the cache for web application [{1}] because there was insufficient free space available after evicting expired cache entries - consider increasing the maximum size of the cache

The problem I have is that my configuration currently reads:
/opt/tomcat/apache-tomcat-9.0.95/webapps/xwiki/META-INF/context.xml 

<Context containerSciFilter="org.apache.jasper.servlet.JasperInitializer">
  <JarScanner>
    <JarScanFilter defaultTldScan="false"/>
  </JarScanner>
  <!-- We need to set the resource cache size since the default (10K) is too small for loading all XWiki resources at
       once -->
  <Resources cacheMaxSize="512000" />
</Context>

Which I understand should already enable the cache to be of MaxSize of 500MB - Which wouldn’t explain why I am still getting an error message, may I know how can I check if I’m doing it right?

Would this be the reason my disk reads are going through the roof?
Are there any other log-files that I am missing in terms of checking the performance/stability of the page?

Thanks.
