We have many resources with 5,000 or more archival object records. We've deployed on some pretty decent Amazon EC2 boxes (16GB memory, burstable CPU, etc.) with negligible improvement. I have a feeling that this is not a resource allocation issue. Looking at the web inspector, most of the time is spent negotiating <span style="color:inherit;font-size:inherit"><a href="http://jstree.com/" target="_blank">jstree</a> and/or loading<i> all JSON objects</i> associated with a resource into the browser.
