Google found that when the results increased to 30 per page ... it took about twice as long to display the longer results list for the user.
I'm surprised that increasing from 10 to 30 results increased total latency by ~100%. I would have expected that other factors (one-time costs like session establishment) would dominate the overall latency, and the marginal cost of fetching 20 additional query results would be fairly small.
- cpr 18y agoThe clue is probably in the 700-1000 machine interaction. If they have to display 200% more results (10 vs 30), they're probably interacting with a lot more machines in their cloud.
- neilc 18y agoPerhaps -- but even if that is true, interacting with more machines is presumably a trivially parallelizable operation, so it shouldn't double the overall response latency.
