Add script with a bunch of common queries

[arj03]

I noticed that I didn't have a very good idea of how common queries are running. This gives us a better idea. Might be good to run in the CI thingy. But for now I'll just dump them here.

Output

running: key initial
query: 199.9ms
running: key 2
query: 25.106ms
running: key again
query: 22.5ms
running: latest root posts

running: latest posts

running: votes initial

running: votes 2

running: author posts

Could we merge this PR only when it's running against ssb-fixtures? This way we can objectively compare numbers across computers, and we don't need to depend on personal data (and their msg.keys), also making it better for other future contributors to run them.

Yes very good idea. Was mostly interested in getting in some good queries that are used a lot in apps.

Or actually, how about folding these into the benchmark/index.js? After all, the goal of these scripts is to check the perf. Then it's easier, just add new tests with these queries

[arj03]

Agree, that's what I meant with the: "Might be good to run in the CI thingy" :-) I'm using this now mostly to test the optimization for prefixes. Once that is done I'll make a proper PR. This was mostly meant as an open invitation if you have any queries from your threads testing but you can of course always add them afterwards :)

@arj03 see above, can we delete one of these? Running it three times doesn't seem necessary

[arj03]

Yes

[staltz]

@arj03 I pushed some commits that move these queries into benchmark/index.js

The idea with the second run is that we test not having to load the index from disc. So it needs to be a another key otherwise we will test your weakmap cache instead.

[arj03]

Other than that it's really good to see these queries here in the CI

[staltz]

Alright, LGTM. How about you review and merge? (note that perf.js was deleted)
