This sounds really interesting, could you provide a bit more detail on the application? Mostly interested in:

- was it over a LAN or WAN?

- how were the latency improvements measured?

- was there a UI on the front end or was this strictly a backend to backend scenario

It was DC environment.

I measure latency on a client, on service and on using some very expensive, cut-through switches. This shotgun method lets me lazily detect where the latency comes from with a single look. I understand not everybody has access to cut-through switching, but for most uses port mirroring is available on a lot of hardware

Strictly backend.
