page size and performance
hi everyone
i am using a fortran code that requires a lot of memory (~10G)
naturally it does allot of swapping to disk which means it works very slowly and i am trying to look for a way to improve that.
(i will definitely get more RAM)
one thing that seems to me might help is increasing the page size to reduce the number of read/write operation.
1. has anyone done that or has any insights on the matter?
2. if so what how is it being done (do i need to compile the kernel or just configure the syste?)
as you can see i am a little over my head here so please be gentle.
thanks in advance.
