Is LevelDB 2 times faster than BadgerDB? (Update: No)

Update (2020/05/21) the method used in this post is totally sub-performant, and I finally found out about LevelDB’s and Badger’s batch methods, which make writes considerably faster, I’ll probably write another note about this. And by the way, I found Badger to be much faster at writing batches than LevelDB. Actual post I’m working on a plugin for Goxplorer that will create a database of all Bitcoin addresses present in its blockchain.
