<p class="MsoNormal"><span style="font-size:9.5pt">We're running into an issue with a large resource record in ArchivesSpace and wonder if anyone has experienced a similar issue. In one resource record, we have a series/archival object with around 19,000 direct

<p class="MsoNormal"><span style="font-size:9.5pt">The slow load time does not seem to be affected by memory allocation; we've tried increasing the speed / size of the server and it seemed to have no effect. We'd definitely appreciate any other suggestions

<div>
<p class="MsoNormal"><span style="font-size:9.5pt">We also wonder if this performance issue is essentially caused by the queries being run to generate the UI view - i.e. perhaps in generating the resource 'tree' view, all data for the whole series (all 19k
archival objects) is being retrieved and stored in memory? If so, we wondered if it would be possible and would make sense to change the queries running during tree generation, etc. to only retrieve some batches at a time, lazy loading style? <o:p></o:p></span></p>
