<p class="MsoNormal"><span style="font-size:11.0pt">We recently migrated ArchivesSpace (2.2.2) from SUSE Linux (11 SP4) to Ubuntu 16.04 for our development server. It has a high CPU usage for Java all the time, averaging (according to top) over 100% (across
two CPUs), which triggers alerts in VMware. Here’s some of the relevant specs:<o:p></o:p></span></p>
