Hey Folks,
In my application, I'm seeing some design considerations in a project I'm
working on that push me towards the use of smaller memory page sizes. I'm
curious - is it possible in practical terms to run DPDK without hugepages?
If so, does anybody have any practical experience (or a
back-of-the-envelop estimate) of how badly such a configuration would hurt
performance? For sake of argument, assume that virtually all of the memory
being used is in pre-allocated mempools (e.g lots of rte_mempool_create(),
very little rte_malloc().
Thanks in advance for your help.
