Subject: Re: [Samba] Samba memory usage - how big is it?
I didn't include the whole output which would be about a page. Yeah
it is just a total of the columns. There is commands for excluding
shared memory regions, "anonymously allocated" parts etc.
Yeah, probably is overkill for samba. We usually have about 16GB of
RAM in use between samba and the filesystem stuff. We are using SAM
QFS to handle hierarchal storage. There is a fair bit of non-sharing
load on the system, typically we have 5 LTO 4 tape drives running
either restoring or archiving data, and 3-10 processes scanning the
arrays for changes that need archiving which use ~140MB each. At the
moment showing a load of 28.5 on the system, busy busy :)

Similar on Solaris, they have a built in utility called pmap:
pmap <pid> gives output just about total virtual memory, ex:
FF3F6000 8K rwx-- /lib/ld.so.1
FF3FA000 8K rwxs- [ anon ]
FFBE0000 128K rwx-- [ stack ]
total 29632K
pmap -x <pid> gives extended info ex:

We are currently running Samba 3.2.4 on our system. I can't remember
what our memory footprint was before we upgraded from 3.0.24. That
said, with the amount of RAM on our system we don't get more than
70%
RAM use at any time, even while driving 2 tape robots and 30
filesystem/raid arrays from the box.
Well, 32GB for just 117 users is just way over the top.
Samba alone should be able to work with a LOT less memory.
How does the Solaris pmap calculate the 29632k? Adding up
the numbers above that I end up at 144k which is probably
too little.
