[Samba] memory optimization for Samba

HI,
I am new to samba internals. I have to port samba on an embedded
target with strict memory constraints. I want to weather or not Samba can
be optimized for smaller memory footprints and if yes how? Can samba be
installed by removing some packages or is there any other version
available for embedded targets?
Any detail provided will be of great help.


Thanks

Right now we're pretty monolithic, sorry. What is more
constrained in your environment? Disk or RAM? We've put
quite a bit of effort into reducing the dynamic memory
requirements with 3.2, but our disk footprint is still way
larger than it strictly needs to be. We're working towards
using more shared libraries for common components, but this
is not fully done yet. We'd appreciate help here :-)

Hi,
Thanks for ur reply. My major constraint is the RAM.
Also i want to know weather samba has been ported to embedded targets with
such constraints(RAM) and what is the minimun RAM requirement for samba
3.2.
If you can guide me towards any good samba 3.2 installation/internals or
optimization tutorials will be of some help to me.

That's difficult to say, as the exact RAM requirements very
much depend on the actual client actions. If I remember
correctly, last time I measured it an idle client added
roughly 300k memory footprint to the running system. I did
not measure though how much just starting Samba was.

For installation, there's tons of stuff around via
www.samba.org. For internals, ask on samba-technical or join
the #samba-technical channel on irc.freenode.net.
