xdelta3 -s LARGE-backup-old.tar LARGE-backup-new.tar delta #156

The (ordinary) tar file is a 30-GB backup taken couple of months apart.  
xdelta3 is very slow, and when the 'delta' file reached about 12 GB I stopped 
it!

Xdelta3 version 3.0.0, Ubuntu 12.04, 32 bit(xdelta does not handle large files 
on this setup, but xdelta3 does.)

QUESTION:   Please give an example(correct memory/optimization flags) that work 
with these large files.  I'm using:
xdelta3 -s LARGE-backup-old.tar LARGE-backup-new.tar  delta

Thank you,
Reza.

Okay, increasing the Source buffer size with -B to 1GB fixed this.

Thank you,
