Ok, here are a selection of the results of my tests. "rs" controls the
number of results asked for.

/service?a=g&t=m&rs=1 200 32ms 39cpu_ms 31api_cpu_ms
/service?a=g&t=m&rs=2 200 44ms 50cpu_ms 44api_cpu_ms
/service?a=g&t=m&rs=3 200 56ms 64cpu_ms 57api_cpu_ms
/service?a=g&t=m&rs=4 200 101ms 82cpu_ms 70api_cpu_ms
/service?a=g&t=m&rs=5 200 53ms 90cpu_ms 84api_cpu_ms
/service?a=g&t=m&rs=6 200 50ms 109cpu_ms 97api_cpu_ms
/service?a=g&t=m&rs=7 200 41ms 117cpu_ms 110api_cpu_ms
/service?a=g&t=m&rs=8 200 57ms 136cpu_ms 123api_cpu_ms
/service?a=g&t=m&rs=9 200 43ms 144cpu_ms 136api_cpu_ms
/service?a=g&t=m&rs=10 200 62ms 174cpu_ms 150api_cpu_ms
/service?a=g&t=m&rs=20 200 47ms 306cpu_ms 282api_cpu_ms
/service?a=g&t=m&rs=50 200 76ms 705cpu_ms 678api_cpu_ms
/service?a=g&t=m&rs=70 200 86ms 974cpu_ms 942api_cpu_ms

Interesting. The variable api_cpu_ms climbs very ... predictably. In
fact, it would seem:

api_cpu_ms = 13.2 * results + 17.5

... rounded off to the nearest millisecond. At least for queries. I
haven't tried straight key fetches.

This is really disturbing.
