Hello, We must change our server to use xwiki. Do you have simple recommandations about requirement ( CPU, specialy RAM because server provided is a VM, ...) to have for a fast xwiki? On this server I will install: - debian stable Jessie - Tomcat 8.5.5 version probably - postgreSQL server - xwiki attachment stored in the filesystem - solr server embedded probably Thxs. Of course I will recheck http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationTomcat and http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Performances Thxs. Pascal B
