Tomcat/XWiki crashes with "out of memory" error on recommended hardware sizing using Debian installation

Hi,

I just installed XWiki on Debian following https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Installation/InstallationViaAPT/ using the xwiki-tomcat9-pgsql package, with the recommended 2GB of memory on the system, as outlined here
and the recommended "Xmx 1024" setting as instructed here.

The system will install & DistributionWizard will run fine, but when trying to edit a page, tomcat will crash with out-of-memory errors.

It would be nice if https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Installation/InstallationViaAPT/ would include actual sizing & memory configuration information that allows for an all-in-one installation & use of XWiki.
Thanks & Kind regards,
