I believe that you will find that blaming this java class is a measurement artifact. If you look at the code, it's a one-line wrapper around other things: https://github.com/DSpace/DSpace/blob/master/dspace-xmlui/src/main/java/org/dspace/springmvc/CocoonForwardController.java
As to whether Cocoon is a bottle-neck, that's a deeper question involving how else you'd get certain things done. If I were seeing things grind to a halt while students were submitting their work, I'd look at decoupling the deposit from the rest of repository using the standard SWORD interface. cheers stuart -- ...let us be heard from red core to black sky On Wed, Jun 8, 2016 at 6:45 AM, Hui Zhang <zhang4...@gmail.com> wrote: > Hello, > > We have an fairly large these and dissertation IR running on DSpace 3.0 > XMLUI, which faced the problem of sluggish speed recently as students start > to deposit their works for graduation.
