RAM memory is not fully being consumed during image processing on UbuntuX86v12.04

Hi there,
I am doing image processing using ADORE-DORIS software. While processing the system is getting very slow. In the System Monitor its only showing around 25% Memory cosumption and Swap not available. Kindly let me know how to utilize full RAM?

Cheers!

If the processes use only 25% of your RAM it means they do not need more. Except if you are running a 32 bit OS on a machine with 16GB of RAM and a PAE kernel.
Most likely the RAM is not the bottleneck, have a look at CPU usage and I/O performance. Since you seem to use Ubuntu I am pretty sure it has a system monitor application installed.

But if the process doesnt need more RAM then why its making the whole system slow? During the processing I checked System Monitor and my CPU 1 and 2 usage were 100%. Do you have any suggestion to increase the speed a little bit? I am using 4GB RAM and 500 and 150GB hard disk.

Do you have more than those two cores? If not then you have your answer, your CPU is fully used by your program, that leaves less CPU time to use for other applications, making the system slow.
Your CPU is the bottleneck, not the RAM.

You are right. I am using dual core CPU. I think that's the reason.
Thanks!
