That's 200x performance in relation to what?

In 200x improvement in random read performance, compared to RocksDB or WiredTiger (MongoDB's storage engine). You can find benchmarks on our website: https://terark.com/en/index And here: https://github.com/Terark/terarkdb/wiki/Benchmark

We also provide a free license of TerarkDB and you can download the exact scripts we used and run your own benchmarks with the configuration you want. We know the claim may sound outlandish, so we try to be as transparent as possible.

Can you please do some benchmarks against MySQL and PostgreSQL? The vast majority of your prospective customers will be using these two instead of RocksDB or MongoDB.

Sure! Our benchmark against MySQL is here: https://github.com/Terark/mysql-on-terarkdb/wiki/YCSB-on-9.1... We used YCSB on 9.1Gb of movie data. This benchmark is comparing MySQL with our product "MySQL on Terark". "MySQL on Terark" is basically MySQL configured with TerarkDB instead of InnoDB -- that way you can migrate your MySQL applications to Terark with virtually no modification in your code.

We do not have any benchmark against PostgreSQL though. It is not in our plans to adapt our storage engine to PostgreSQL, so we're not comparing it against it, but the gains are just as significative.

I hope that answer your questions, and feel free to reach us at business@terark.com
