[Archivesspace_Users_Group] performance issues

Mon Sep 22 11:11:18 EDT 2014

Somehow, I missed this response until now. I will implement these changes as soon as I can. Hopefully, I'll be able to report visible improvements. Thank you very much!

Hey Douglas,

So, off the bat I'd suggest upgrading to Java 7, which is recommended version for Aspace. I'd also suggest using Oracle java instead of OpenJDK, as I think most people see much better performance. 

Also, since you have 4G of RAM, you can bump that heap up from 1024m, probably to 2G or even 3G. Without changing the heap, the application will only use that 1G allocated to the java heap. You can do this by setting the ASPACE_JAVA_XMX system variable to '-Xmx2048m'.  Bumping the PermGen to 512m might also help  ( ASPACE_JAVA_MAXPERMSIZE ). 

I'd try those fixes first, and I'm willing to bet you'll see some improvement..

b,chris.

This is a default install of aspace running Jetty.
The last test migration was a few weeks ago, so I would have thought all indexing was finished long ago.
We have a local mysql: mysql  Ver 14.14 Distrib 5.5.38, for debian-linux-gnu (x86_64) using readline 6.2 We have 27G disk available on the 4-core/4GB Ubuntu KVM VM.

More details below. Thanks very much for looking into this!

Hi Douglas,

Some quesitons: what is the heap space settings? are you running with jetty or tomcat?  and have you made any tweaks to the default setting?

What your seeing in the logs indicates that the system is indexing the records. Did you do a migration recently?

b,chris.

Subject: [Archivesspace_Users_Group] performance issues

I've not found the aspace interface to be fast enough for production use. Some of the retrievals it does while browsing take long enough that I wonder if I'm accidentally running in some sort of debug mode. Does such a thing exist? The VM our pilot is on is a 4-core/4gb instance which should be overkill for the six users we have during the pilot. Log spam in general is pretty bad with aspace, another reason I wonder if I'm running in some kind of debug mode.

Frequently I notice that java claims all the cores and the machine really begins to lag. I looked at the solr interface without really knowing what I'm looking for, is there some info there which would help me figure out what is locking up the java process?

At present the system is making log entries like "Indexed 12325 of 37427 archival_object records in repository University Archives" but I didn't delete the index to force a new one and I'm not sure why re-indexing would take so much processor time when we aren't changing anything.

Thanks in advance for any suggestions as to how to diagnose the poor performance.
