Just out of curiosity, would it be possible to know some more details
about that benchmarking? Such as:
- was the queries done from the server itself? 1 external client? many
external clients? And were the external clients connected to the same
network as the server, perhaps connected to the same switch the server was
using? 100Mbps? 1Gbps?
- was it asking for locally cached data, or did the server need to go out
and query for some external data? And what was the normal size of the
- what kind of hardware (especially CPU + speed) + OS was the server running?
