iQ-Views server decompresses the images by default AFTER reception. The transfer was using JPEG Lossles TS as you can see.

You can add the additional parameter -nd for no-decompression if you want to store lossless compressed images in your local imagebox.

K-PACS server does not have an on-the-fly decompression option.

Regards,
Andreas
