This is interesting and I will investigate. Did you set the -B flag to its
largest value (i.e., 2GB?)
I would like to update the xdelta3 source to optionally use 64-bit addressing
internally, to support -B > 2GB which would help here.
There may be deeper issues related to the specific organization of an ISO.
Xdelta would perform better, I suspect, if it recognized that ISOs are
containers of smaller files-- it would encode per-file differences.
SmartVersion may be doing this?

I have a branch of xdelta3 w/ support for 64bit checksums, I put it on github:
https://github.com/jmacd/xdelta/tree/64bithash
This lets me set -B 4GB, which makes the whole source file visible, which
yields better results.
a) 618KB
b) 12MB
I'll release this in 3.0.9 after more testing. Thanks.
