Hello Andreea, If you are still experiencing less than ideal performance, we have some notes on improving the performance of DSpace by providing more memory to it: https://wiki.duraspace.org/display/DSDOC6x/Performance+Tuning+DSpace While the *minimum* values there are good for brand new sites, as you site grows in size or has a large number of users, you really should be looking at allocating several GB of memory for Tomcat alone. Very large or very active sites tend to be in the 2-4GB or more range. If your memory allocation is too small, your site performance will suffer, and DSpace will become slower and slower.
It's hard to say if this is your exact issue, but it's usually the first thing to check when performance is less than ideal. Others on this mailing list may have more specific advice to add here.
