xDL version 3.4 has been undergoing testing since mid-spring, 2010. During that time the xDL was tested under an average volume load of approximately 1,600 studies per day, 7 days per week. Peak hour loads 3 times the average daily volume were observed and handled efficiently. These studies were generated by a variety of modalities of different makes and models; the studies supplied on a daily basis by an academic partner over a 1 Gbit connection. Individual studies as large as 2.5 GB (compressed) were handled routinely. The average size of studies tested was 65.8 MB (compressed) and the average study contained 295.1 images. This performance was achieved with an Dell rack computer with a single E5620 2.4 GHZ Xenon processor and 4 GB of memory running in a virtual environment with a single core assigned to the xDL.

The software was released in early October and roll out to existing customers began the end of October.

Wayne DeJarnette, Ph.D., company president commented: "This level of performance is well above the vast majority of PACS archive software currently deployed. As the leader in the PACS migration market, we get to see the ingestion capabilities of all the PACS archives in the marketplace; xDL 3.4 seems to out perform them all."
