Hi everyone,
I have a question about the 64Bit mode in AMD 64bit
My question is if I run a 32Bit application in Optreon AMD 64Bit with Linux 64Bit does this give my any benefit ? I mean running 32Bit application in 64Bit machine with 64 Linux is it better that running it in 32Bit or doesn't make any different at all ?
Thanks
Hi
Running a 32 bits application on a x86_64 kernel gives more virtual address : 4GB of user memory, instead of 3GB on a standard 32bits kernel
If your application uses a lot of in-kernel ressources (like tcp sockets and network buffers), it also wont be constrained by the pressure a 32 bits kernel has on lowmem (typically 896 MB of lowmem)
If your machine has less than 2GB, running a 64bits kernel is not a win, because all kernel data use more ram (pointers are 64 bits instead of 32bits)
