You are right, I should have elaborated on those claims, and I plan to add a relevant Wiki page to address this shortcoming. However, you can use the tank-cli bm command to benchmark client to broker to client (end to end) latency. We get sub-ms (a few hundred microseconds) latency here, and even on a very busy Tank broker (it takes effort to get there), I don't foresee situations where you can get over 1ms latency for any operation. For throughput, Tank relies on sendfile() and readahead() for very high throughput - and thanks to the very tight packing of the messages, you will likely saturate your disk/network easily.
