performance with huge files

[daniel wilson]

Hi all,

I'm working with some very large files, 500GB or thereabouts, using
rsync 3.0.7.   I'm not familiar with the internal operation of the
rsync protocol, but I've read a few old posts that suggest there may
be ways to improve performance.

Can anyone give me pointers to config changes or patches that might
help reduce the CPU burden when working with such large files ?

Thanks in advance,

Dan
