Hello all,

A recent thread on 'dspace-tech' mailing list (see: 
http://www.mail-archive.com/dspace-tech@lists.sourceforge.net/msg11969.html) 
has brought up the question of DSpace 1.6.x's performance and memory 
usage.  We've already had mention of potential performance issues 
(memory leaks, mostly), and the occasional need to restart Tomcat 
relatively frequently.

As DSpace Software is built/maintained entirely by an all volunteer 
Committer team, we occasionally need to rely on our large user community 
to help us track down issues that our individual Committers may not yet 
be encountering in their local DSpace installations.

Therefore, I'd like to ask all of you on these lists for open discussion 
and community feedback around what issues you may be encountering in 
regards to DSpace Performance and/or Memory Usage.  We welcome any 
constructive feedback you can provide, along with any hints/tips you may 
have discovered in your experiences.

I've added a general template to report your DSpace performance/memory 
issues (or even resolutions, if you've found them) on this wiki page:

https://wiki.duraspace.org/display/DSPACE/ScalabilityIssues1.6

You are welcome to report your issues (using that template) either on 
the wiki itself, or by sending an email to this mailing list.  You'll 
notice, as a part of this template, I've asked if you'd be willing to 
volunteer time to help resolve the issues.  My hope is that we can start 
an "interest group" of volunteer developers (or other semi-techie folks) 
who can start to work together more closely to share info and tackle 
these issues.

Thanks all!  I'm hoping this can help us to "jump start" the process of 
finding a resolution to any memory leaks or performance issues that may 
existing in the current DSpace software.  But, it does take volunteers 
to make this happen quickly!  Please share your issues & what you've 
found, but also think about volunteering some of your time/expertise. 
Who knows, you might even find it may result in an invitation to become 
our next DSpace Committer (thus providing you and your institution more 
of a "say" in the future of DSpace software)!

[As a related sidenote:] if you aren't already aware, we also have a 
System Administrators area to our Wiki where any DSpace System Admins 
are encouraged to share their hints/tips/configurations/setups.  Please 
feel free to take a look at it, and think about sharing your own 
hints/tips with others.  Anyone is welcome to create content or new 
pages in this area:
