When I modify a study (to anonymize for instance) My workstation is pretty much useless until it is finished as it is using all available CPU resources. It also takes too long to edit the data. Typical time to anonymize a 300image CT study is over 10 minutes. This did not happen with the older builds of the software.
Since I need to use K-PACS as part of a QA process where users will routinely be editing demographic data this performance is preventing us from going forward with our project.
