Obviously self-promotional, but Parsyncfp?

There are other like scripted parallel rsyncs, but I like this one. ;)

Using multiple connections also helps when you have LACP network links, which
are relatively common in data center setups to have both redundancy and
increased bandwidth.
If you have two 1Gbps links aggregated

SPDY has apparently evolved into QUIC. QUIC supports multiple streams, which
can be created by either end. There can be a huge number of these. It seems
like a sender of

Multiple connections also makes sense on high bandwidth links. I’ve never been
able to rsync at wire speed on a 40G link using only one connection.

I made a bash script doing this in parallel, checks how many rsyncs are
running and then starts another 'concurrent one'. My parallel sessions
are against different servers. I doubt if it would make any sense doing
multiple sessions between the same two hosts. My single rsync sessions

The issue when copying a large number of small files is disk IO / seeking.
Check the wait for IO values using top / whatever when doing such a transfer.
Running multiple threads in such a situation will only cau

+1 from me on this.
We have several situations where we need to copy a large number of very small
files, and I expect that having multiple file transfer threads, allowing say ~5
transfers concurrently, would speed up

I also vote for this feature. Using multiple connections, rsync can use
multiples internet connections at the same time.

Another proven case is your typical modern web browser.

Actually having two or three TCP streams at the same time has proven to be
faster, because it can scan ahead. It is proven that if you download one large
file, while downloading several

I see this is quite old, and to be honest I'm not completely familiar with
rsync's implementation, but more rsync performance is of benefit to everyone so
I thought I'd chip in my thoughts.
