There is also a good write-up [0] by Julia Evans. We ran into this with DICOM storescp, which is a chatty protocol and TCP_NODELAY=1 makes the throughput significantly better. Since DICOM is often used in a LAN, that default just makes it unnecessarily worse.
Oh, DICOM really like to talk back and forth... I guess that nowadays it should be better with all the WEB/REST versions of the protocol.
Oh! Thank you for this! I love Julia’s writing but haven’t read this post.
I wonder how this fix could be implemented without source code access. Suppose an old ct scanner is clogging up the network.
