Tony, 1. As you mentioned, we don't see any benefit to runtime selection of the storage engine; thus the indirect call is unnecessary in our environment. I'm curious about this choice. Have you tried to benchmark the benefit of using a compile-time choice of a storage engine vs. indirect calls at runtime? Do you happen to have any statistics on hand regarding whether that change consistently influences latency/throughput? We haven't done any benchmarks. However, as I understand Toru and Trond's design, I suspect it would not be particularly expensive. Because the key is at a fixed location no matter the storage engine, the assoc_find call would not need to call into the storage engine. Thanks, Tony
