[Unison-hackers] File transfer using an external program

[Jerome Vouillon]

Hi,

Has any benchmark been performed regarding the support for invoking an
external file transfer tool?

I thought Unison was fairly good at transferring large files.  File
contents are sent in 64 KiB chunks using a synchronous RPC mechanism.
So, over a fast high-latency connection (DSL, for instance), Unison
may be somewhat latency bound when synchronizing a single file.  But I
would expect it to use the full bandwidth when synchronizing two files
or more.
