This reduces + the Orthanc overall CPU usage and latency. This is suitable for setups with large + bandwidth network like LAN. + - When "HttpCompressionEnabled" is true, only the content that is clearly identified as + compressible is compressed (JSON, XML, HTML, text, ...). DICOM files are never + compressed over HTTP. In prior versions, all content types were compressed. + This notably greatly improve loading time of large DICOM + files through WADO-RS e.g in StoneViewer when working on large bandwidth networks. + - When "HttpCompressionEnabled" is true, content < 2KB are never compressed.
