[Samba] Question regarding sizes of of Samba for SuSE Linux

[Francis Wilson]

My high school computer lab has a Samba file server, currently running 
SuSE Linux 9.3; over the summer, I plan to wipe out the hard drives and 
install SuSE Linux 10.0; with this in mind, I have just downloaded the 
latest Samba, and I was struck by the tremendous difference between the 
relative sizes of samba-3.0.5 and samba-3.0.22.

6,413,555 samba-3.0.5-0.1.i586.rpm          10/01/2004  04:54 PM
3,012,340 samba-3.0.22-6.1.14.i586.rpm   04/27/2006  08:18 AM

Is something wrong?  Can someone explain why the newer version is less 
than half the size of the older version?
