[Archivesspace_Users_Group] related records

Hi Brian, 

Yes, in this particular case, there are several thousand siblings, all children to the same parent (the resource record). In a few other cases, we have an equivalent number of objects, but arranged into parents series, so a little more structured.

Hi Ben, 

Does the collection that is causing this have a large number of sibling components? In other words, what is the maximum number of components that all share the same parent?

Hi Chris, 

Looks like the issues are on the client side in Chrome. A lot of 200s. Harder to tell in Firefox, though the Network Monitor in Firefox appears to be a little more detailed . I've attached screenshots here. 

I don't want to belabor this issue at everyone's expense. I just want to get an idea of what ASpace can handle in terms of treesize/attached records. Obviously, we're all going to have a few outlying, extremely large resource records to deal with, though. 

Thanks, 
Ben

Hi Ben, 

This could be the result of a few thing. 
First off, on the server-side, you can adjust the java heap space settings by adding a ASPACE_JAVA_XMX ( or a Xmx setting to your JAVA_OPTS ). This will depend on how much RAM you have on your system.Performance can also vary depending on the number of processors you have on the server. 

All that said, what you're probably seeing is actually on the client-side. That is, ASpace is giving your browser a bunch of data that is killing your browsers javascript engine. 

So, are the 5000 AOs directly associated to a single parent, or is this a tree of objects with multiple parents? And do the individual records have a lot of subrecords associated to them? Such as instances, agents, or subjects? 

You can see this by looking at the network status ( Tools => Web Developer => Network in Firefox, View => Developer => Developer Tools => Network in Chrome ). You should see all the requests that the browser is sending here...if all the requests are getting a "200", then it's the browser's dealing with the JS that's causing the issue...if you see a request that just hangs in "Pending" status, then the issue is on the server side. 

Does that make sense?

Hello, 

We are still having this issue in 1.2 on collections with large numbers of archival objects and/or large numbers of related records. What I'd like to know is whether any local configurations could be adjusted to increase performance. 

Thanks, 
Ben

Hello, 

We've had similar issues at DU with our collections that have large amounts of archival objects attached. Any sort of editing we want to do in those collections is greeted with the same "Loading..." message that never resolves itself. We notice it generally in collections with more than 5,000 archival objects, though we've had problems with smaller collections if we have many active users at a time. -k

Hi All, 

At Penn State we've noticed some issues with opening resource records that have a large amount of related records. I would have to do some further digging to know how common such a case is, but just to provide one example: we have an institutional records collection with a couple hundred name records and maybe 80 accession records attached. When we click to Edit the record, it seems stuck on "Loading..." 

I should mention that we're currently in the middle of migrating to v1.2, so maybe these issues will be addressed, but I am wondering if anyone has encountered any challenges with an excessive amount of related resources, or whether there is an optimal amount or limit (?). 

Thanks, 
Ben
