	I was just responding based on my experience with suse, where in the delta rpm world, the config file finally came with the following caution:

##
## Whether to consider using a .delta.rpm when downloading a package
##                                                                  
## Valid values: boolean                                            
## Default value: true                                              
##                                                                  
## Using a delta rpm will decrease the download size for package updates
## since it does not contain all files of the package but only the binary
## diff of changed ones. Recreating the rpm package on the local machine 
## is an expensive operation (memory,CPU). If your network connection is 
## not too slow, you benefit from disabling .delta.rpm.                  
##                                                                       
# download.use_deltarpm = true                                           
download.use_deltarpm = false                                            


	I was talking about the same thinking applied to pacman packages ;-)
