Hi David, Also see the following "Performance Tuning" page on our wiki for suggestions on how to avoid 'PermGen space' errors:
https://wiki.duraspace.org/display/DSPACE/HowToPerformanceTuneForDspace As of DSpace 1.7.0, we recommend the following minimums for optimal DSpace performance: Java Heap Memory (-Xmx and -Xms) should be set to >=512MB Java PermGen Memory (-XX:MaxPermSize) should be set to >=128MB Again, these are the *minimums* we recommend for optimal performance (it may be possible to run on less memory, but performance will not be optimal). Also, if your DSpace will be storing lots of items or having a lot of simultaneous users, you actually may need to increase these values. Instructions on how to set those are on the above wiki page. - Tim On 1/19/2011 8:20 AM, Mark H.
