Thanks for the pointer. I've re-compiled with
define STREAM_BUFSIZE (NETWORK_BLOCK_BYTES * 16) And I can see that has taken effect on the server dumper: try_socksize: send buffer size is 524288 But backups are running no faster and I cannot see any indication on the client of the buffer size being used. Note: client also has the new binaries. In older versions of AMANDA amandad used to report buffer size, but this appears to not be the case in 2.6.1p1.
