I don't think writing a clickbaity title like this is fair. You just write 200k large documents per second, period. Good for you but to be blatantly honest it's actually not a lot.

I'm not saying you shouldn't have written this post, but rather suggest you be fair to your readers (and yourself). Otherwise you could just make up random titles like "Writing 1 trillion log lines per second" (by storing 1,000,000 1-byte, newline-separated log lines per document).
