Benchmark your MT with /emergeblocks

[Fixerol]

Decided to do very little and simple benchmark, to do it:
1. run clean minetest without config/cache
2. create world: seed: 1, mapgen v7
3. start it
4. look up on game start, press t and type: /emergeblocks (0,0,0) (-1000,-1000,-1000)
5. wait around 20 min... don't do anything at this time
6. at the end you will get "Finished emerging 262144 blocks in X msec (on screen/in chat console)
7. post your results with hardware specs, os, minetest version

My results:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

This error was from the daily build from the Ubuntu PPA. My self compiled version run's without any problems.

But this "benchmark" is pretty useless because it only benches one part of Minetest. But it is interesting to see that not all areas are generated with the same speed. It took a long time e.g. from 40% to 42%, but from 42% to 48% it was fast. Would like to know which areas took so long.

And it is not consistant, however. First I run with sqlite3, which needs 1250 seconds. Then I replaced the backend in world.mt with dummy. This time it tooks 1650 seconds. Then I try leveldb which also needs over 1600 seconds. Just to confirm my first result I set the backend to sqlite again, delete the db file and run again. Over 1600 seconds.

So what does that mean? I don't know

Ha, this is just an experiment :)

How dumb we are? ;-)

No, it is really an interesting experiment, but not a competition
