+#### Query Performance
+With the [data loaded above](#loading-performance) on the same hardware,
+it took **270ms to run** the pretty complicated query above the first time after server run.
+Note that the json conversion step has a bit more overhead than captured here.
+```json
+{
+ "server_latency": {
+ "json": "57.937316ms",
+ "parsing": "1.329821ms",
+ "processing": "187.590137ms",
+ "total": "246.859704ms"
+ }
+}
+```
+
+Consecutive runs of the same query took much lesser time (100ms), due to posting lists being available in memory.
+```json
+{
+ "server_latency": {
+ "json": "60.419897ms",
+ "parsing": "143.126\u00b5s",
