I tried running Sun Java System Web Server 7.0 update 3 on Debian Lenny . Here is top output :

Simple Web Server (core) without web container :
VIRT RES SHR %MEM
76392 12m 5204 5.1

Simple Web Server (core) with WebDAV without web container :
VIRT RES SHR %MEM
76864 13m 5500 5.2

Simple Web Server with web container :
VIRT RES SHR %MEM
588m 107m 19m 42.7

where
%MEM - Memory usage (RES) A task's currently used share of available physical memory.

VIRT - Virtual Image (kb) The total amount of virtual memory used by the task. It includes all code, data and shared libraries plus pages that have been swapped out.
VIRT = SWAP + RES.

SWAP - Swapped size (kb) The swapped out portion of a task\342\200\231s total virtual memory image.

RES - Resident size (kb) The non-swapped physical memory a task has used.

SHR - Shared Mem size (kb) The amount of shared memory used by a task. It simply reflects memory that could be potentially shared with other processes.

Nice reading and great summary! Thanks so much. In addition to performance and scalability, what's interesting about Sun Web Server is that its support for heterogeneous (native and Java) dynamic web technologies, coupled with its manageability and ease of deployment.

Glad to see you had good experience with Sun Web Server. Also interesting is your perspective on the software business model (the word freemium comes to mind!).

Cheers.

Good question. You can check Sun's website for the recommended technical specs. I will say that my entire headless Debian system with Sun's Webserver, Postgres 8.3 and a couple of other utilities running, is only using 745.86 MB of Ram. With 2G available, I am not close to going to swap yet. I have five virtual hosts set up with Java apps on three. Hope this helps.

What kind of memory footprint does Sun web server use ? My hosting environment (VPS based on Xen) is memory constrained so I have been using Nginx over Apache. However, I would like WebDAV and some other goodies.

About six months ago when I tried Open Solaris with some SATA drives, I could not get it to load. After reviewing the Open Solaris web site, it seemed that only a few Sata Drivers were supported. I have yet to have trouble loading Linux on anything. I realize Linux and Solaris are different systems and Solaris has been in the large enterprise for many years running mostly on Sun hardware.
