[Qemu-devel] OS with only segmentation - will it be faster?

Hi, This is not strictly qemu related but I think people who have a good idea about it must be on this list. I was wondering if I had an app that requires a fixed quantity of memory - sufficiently less than the available physical memory. Would it benefit from getting rid of the paging mechanism in

Let me see if I understand this right - qemu loads the a.out and begins to interpret the x86 instructions in the a.out and when a system call happens, it makes the call the host system is that right? On Wed, Aug 11, 2010 at 2:12 PM, Stefan Weil wrote: > Am 11.08.2010 10:31, schrieb
