In my experience with Samba, the more ram the better. Samba spans a child process for each connection. I set up a Samba server for about 60 users on a RedHat 7.0 box with two 266 P2 processors and 128megs of ram and had nothing but trouble. I then used a Dell 1300 series server running RedHat 7.0 and with a 550 P3 processor and 512 megs of ram, and it has ran flawlessly (under heavy usage) for a couple of months now. Not to mention it is noticeably faster than an NT server on the same hardware. I have noticed that CPU utilization on the server is seldomly very high, but you should have a minimum of 128 megs of ram and allot an additional 3 to 4 megs of ram for every user to achieve good performance. Realistically I would say one server for every 200 users or so (under heavy usage). Forrest Dickinson Network Administrator Morgan Hunter Companies (913) 491-3434 I am curious to find out how large (in numbers of users) samba can realistically support on 1 box. This box could be a monster machine, 4+Gb RAM, RAID array, etc.. Anyone have some numbers to throw out? 200, 400, 1000 users? I am not finding much of whitepapers on the 'net. -- Bob Tanner <tanner at real-time.com> | Phone : (952)943-8700 http://www.mn-linux.org | Fax : (952)943-8500 Key fingerprint = 6C E9 51 4F D5 3E 4C 66 62 A9 10 E5 35 85 39 D9
