Compression Service: The Compression Service supports delayed, lossless compression of received images. This is an alternative to immediately compressing images when received. (The lossless compression rules are configured by the CompressionRules attribute in the StorageSCP service.) The value of the MaxConcurrentCodecattribute in the Compression Service also effects the on-the-fly compression and decompression during the receive and retrieve of images by the StorageSCP and QueryRetrieveSCP services. (For details, see the MaxConcurrentCodec attribute below.) Also see the CODECs page in the dcm4che14 documentation.

MaxConcurrentCodec
Maximum number of concurrent tasks for compressing and decompressing images. When the default value is of MaxConcurrentCodec is 1, all compression and decompression operations are serialized. For example, if on-the-fly compression during an image receive is activated, and three modalities concurrently send uncompressed images to the archive, only one image received from one modality is compressed at the same time. This significantly reduces the receiving performance. The used codec allocates memory for uncompressed pixel data of at least one frame, so without limiting the maximum number of concurrent compression tasks, memory consumption could become unacceptable. You will receive an out of memory error if the memory consumption exceeds the configured{{-Xmx}} value in the dcm4chee_home/bin/run.conf file).
