[Insight-users] Watersheds performace in Debug mode

Hi Wassim,
It seems that you are working on Windows.
Is that correct ?
Did you complied the code in "Release" mode ?
The closest machine I have to yours is an Ubuntu Linux
machine with 1Gb of RAM, with a Pentium 4, 3.0Ghz.
When running the program in this machine, compiled with
Gcc 4.1, in Release mode (as setup by CMake), the memory
usage of this process peaks at 622Mb, and it completes
in 18 minutes 37 seconds.
Depending on what other processes you have in memory,
your computer may be swapping memory to disk.
Please keep the Task Manager open while you are running
the program and take a look at the "Performance" tab.
From that, you should be able to verify if the system
is swapping or not.
Please let us know what you find.
Thanks
Luis
