It depends on the datastructure. If you use rte_hash, with the thread safety flags, it's safe.
In any case having a lot of cores accessing the same DS will lead to bad performance. You should try to have per-core data structures whenever possible.

I have tested it by sharing a small structure with two variable and incrementing them in all logical cores. It ran smooth I didn't get any issue. But I doubt if we can run it for long time with some huge data structure having many elements getting accessed by multiple logical cores. Can anyone please clarify this. Thanks and regards, Hemasai.
