Memory footprint
Hello All,
We're working on some middleware that will run on embedded devices. We
need to consider memory footprint before using the Axis2 system. What
is the typical memory footprint that a simple echo app uses for each
module? We will be using the http sender and receiver.
Thanks,

No more than 200-300 KB footprint for the client runtime just to do SOAP
operations. I like the generated soap serialization/deserialization
from WSDLs but I cannot afford to use 2-4MB for this because the system
only has 4 MBs.
Thanks,

Supun,
When I run echo without debugging symbols, I can see a slight
improvement in the memory footprint. It comes down to 3280k from 3924k
on my WinXP. Similarly Simple Axis2 server memory footprint comes down
to 3388k from 4140k.

I think I have made a mistake in previous mail by looking at GNOME System
Monitor to get the memory used by simple axis server. I found this mail with
the subject 'HowTo: Profile Memory in a Linux System'[1] while searching the
net. Using the ps command mentioned in that, I have found following values
in Ubuntu Linux 8.04.
Simple Axis Server:
RSS : 1780KB
VSIZE: 3420KB
Echo Client(I used a sleep call after doing the actual request using
axis2_svc_client and measure the memory taken by the echo process):
RSS: 1808 KB
VSIZE: 3104KB
Definitions:
---------------
RSS (Resident Set Size) - The portion of a process that exists in physical
memory (RAM). The rest of the program exists in swap. If the computer has
not used swap, this number will be equal to VSIZE.
VSIZE (Virtual memory SIZE) - The amount of memory the process is currently
using. This includes the amount in RAM and the amount in swap.

A echo client invocation uses 3440k of memory in my Windows XP machine. I've
tested this with the math sample as well. It also consumes equal amount of
memory. Also the memory foot print for the simple axis2 server is in the
same range.

Re: Memory footprint

Hi,
I did some simple tests to find out memory footprint. Here are the results:
Simple Axis2/C Server(Sleeping): 400KB
When I run echo sample simple axis server takes 472KB memory even after echo
requests are handled.
There may be memory leaks in simple axis server because most of the time we
use it only for testing purposes. If you want to use simple axis2 server, I
think we'll be able to fix those leaks.
Thanks
Milinda
