I want to reduce the total virtual memory in the system and not the physical memory. I have 512Mbyte of RAM in my RHEL 4. I want: Physical memory = 512Mbyte ( as it is) Virtual memory = 1GB. ( reduced it to 1GB from default) I want to see the effect on page tables size, my application and its performance due to the reduction of virtual memory (if any) Regards, Parav Pandit __________________________________________________ Do You Yahoo!?
