Thanks Jim for the consideration.
I humbly suggested the ideas, since we had a similar issue when creating
AF_XDP_ZC PMD. Happy to share ideas.
Thanks

Hi Vipin,
Thanks for your quick reply. I will respond to your queries in order.
1. Yes, in at least one case we have buffers of size 4096 bytes. Some of our
other buffers are much larger (>64KiB)
2. These buffers are used in the I/O path, so performance is very important.
Allocating and freeing
Hi Seth,
If I may I would like to suggest and ask a query on the mempool alignment
details. Please find my suggestion and query inline to the email.

Hello,
In SPDK, we use the rte_mempool struct for many internal structure collections.
The per-thread cache and ease of allocation of mempools are very useful
features.
Some of the collections we store in SPDK are pools of I/O buffers. Typically,
these pools contain elements of at least 4096 by
7 matches
