Hi fellas - Just my 2 cents here. I experimented with this also a while back and with: socket options = SO_SNDBUF=65536,SO_RCVBUF=65536
in my rsyncd.conf on the server side, and: --sockopts=SO_SNDBUF=65536,SO_RCVBUF=65536 as a part of my rsync command line on the client, I get almost 2x the throughput on local gig ethernet. It was a huge improvment... Chris ----- "Neal B" <nrb...@gmail.com> wrote: > Hi Ryan, > > Thanks for your reply.
