If this is between 3.2 and 3.5, nope, I haven't checked.

Good point. At this moment I've built 2.2.12, v3-0-test and master for a quick
comparison. Without starting any of the daemons yet, a quick comparison of
the binary size in MB (built with ./configure --prefix=$SAMBADIR/<version>
and installed with make install):
2.2.12 v3-0-test master
------ --------- ------
smbd 2.1 4.3 11
nmdb 0.8 1.4 3.9
winbindd 1.3 3.0 8.3
I'm going to assume that for a system like that, a "typical workload" will be
five clients reading/writing files in security=user mode (most NAS boxes use
security=share, but I'll consider that broken and use the next best).
Do we have any tools that can simulate a workload like that or do I need to
set up some VMs for this?
