In his test, it appears the Mongo driver is just putting the message on the wire, not actually waiting on the server reply or verifying that the command was ever actually processed. Using the Redis in pipelined execution mode would be a much closer test.

I wouldn't say it's completely useless as it shows that Mongo is faster in a single threaded process, using the most popular ruby client of each system. If I were writing a high-concurrency multi-threaded system to handle millions of keys at a time, Ruby would not be my first choice by far.
Ok, I agree with antriz's statement. My results are very specific. I will make note and be sure to be very thorough next time around.
Thanks for agreeing, however I must point out that since your blog post does not accept comments, nor you rectified the content, this is misleading information that will stay on the internet for virtually many years to come.

#23I think I heard a distant scream of Zed... http://zedshaw.com/essays/programmer_stats.html He was so right for cases like this...
I'm a programmer, but not very good at statistics (as in I passed the class with flying colors, but I can't really comment on new situations).
When it comes to things like benchmarking, I find it easiest to avoid making absolute conclusions like "X is faster than Y", but to merely present the data, all the data, and nothing but the data.
In this case, I'd have wanted to see the response times per request, and perhaps the memory trend for the client. At the very least, I'd like to know how Mongo and Redis were setup, and if either had begun to swap.

I think that meme is funny too, but lets keep meme only posts over on reddit.
Sorry. I'll remember in the future that Hacker News is no place for humor.
Thanks! That's a fine executive summary. The longer version is that original humor is appreciated, particularly if insightful and non-obvious, but regurgitated memes are not welcome here. If you are rushing to make the obvious joke before everyone else does, please don't.

Seriously. I did not know that the use of a meme is violates site ethics guidelines. I checked the comment guidelines (http://ycombinator.com/newsguidelines.html) I didn't see any guideline referring to the use of memes. If using a meme is such an egregious offense as this comment thread suggests, maybe this violation should be mentioned in the guidelines.
Generally the popularity of a comment is a good enough indicator of how well a comment is received. If I got 100 upvotes on that comment I may get the impression that people like that. Considering I have < 0 on the comment, I can take the hint. I don't need the proper patrol reprimanding me about a non-stipulated rule.

#27Can you post the Redis configuration you are using?
