Hi,
There are no known general issues with XWC regarding slow performance. Please submit a support ticket for the issue so that we can investigate the problem in more detail.

We have been seeing slow user authentication since the last major XWC release and seems to be getting slower by the day. Print performance is also very slow. 1 minute to release a single 1 page document is not right. Has any one else been experiencing this?
