What to watch
The database only ever sees the misses. At an 85 percent hit rate it takes about 30 requests a second out of 200. Drag the hit rate down to 0.3 and it is instantly over its 133 a second ceiling, with no change in load at all.What it is made of
Under load
Measured by running this design through the simulator at multiples of its own offered rate of 200 requests a second. Twenty seconds of simulated time, one fixed seed, so the same numbers come out every time.This design holds 800 requests a second with 0% errors. At 1200 it is losing 3% of them.
