Sue, I'm not denying that there is an efficiency problem / bug in DSpace to be bombing out on a minor Collection change just because of the number of Items.
But 256 / 512Mb really is virtually nothing these days. I can easily exceed that editing the DSpace source in an IDE. I'll regularly see my web browser running higher than that after I've been using it for a few hours. Admittedly, I'm running 24(?) DSpace instances in my Tomcat server - but it's on an 8Gb machine, running a 64-bit JVM, currently with a max heap of 4Gb. And these servers - with multi-cores and using commodity RAM - are amongst the cheapest you can buy these days. Thornton, Susan M. (LARC-B702)[NCI INFORMATION SYSTEMS] wrote: > Very interesting.
