I suggest you read a USENIX paper on slab allocators in Solaris, which
are similar to your pool concept.  Of particular note, the page
coloring/cache line considerations could be useful.

 * "The Slab Allocator: An Object-Caching Kernel Memory Allocator",
 * Jeff Bonwick, Sun Microsystems.  In Proceedings of the Summer 1994
 * USENIX Conference Proceedings, Boston, MA, pages 87--98.
