Documentum Webtop 6.5 and later versions enable administrators to specify HTTP or UCF content transfer for different users within the same Webtop installation. Before Documentum ECM 6.5, all users within the same Webtop installation had to use either HTTP or UCF content transfer.
UCF content transfer is more usable and performs better. The following lists the UCF enhancements since Documentum ECM 6.5:
Reduction in the number of round trips between the UCF client and server. This feature is especially effective for improving transfer performance for smaller files over a high latency WAN.
The following UCF client initialization/startup improvements:
Sharing a JVM instance across multiple web sessions
Starting JVM upon login
Support for PDF byte streaming through a native viewer.
Use of parallel streams to increase content transfer rate. This feature is especially effective for improving content transfer performance of large files over a high latency WAN (outbound and inbound).
Freeing up stuck threads to optimize resources and increase concurrency.
Reduction in unnecessary WDK UCF client calls.
An improved content transfer dialog shows the action that is running (in the header of the dialog), the file which is transferring at the time, and progress of that transfer. The new dialog is easier to understand and is similar to other applications with which a user may be familiar.
