Lock free algorithms do re-tries and in addition there seems to be atomic counter upgrades. It seems that the patch runs about 10x slower than the current alloc/free code in repo … if these numbers are correct …

That's a fairly natural means of using queues as a synchronization mechanism. Busy waiting on a queue seems wasteful whether or not we call it a "polled" queue. What seems to exacerbate this issue with the new buffer pool code is that odp_bufffer_alloc() and odp_buffer_free() are now lockless (thanks to the new odp_atomic_internal.h) and so there's less lock-stepping as threads fight over the pool lock for buffer allocates and frees. I suspect the latter tended to serialize things a bit more which smoothed these race conditions out a bit.
