To me this reads as relatively diplomatic for DHH. The interview in question is pretty critical and while DHH seems to suggest that scaling like this is going to suck rails or otherwise he does not address all the criticisms head on and his tone is slightly conciliatory. I guess there's not a lot he can say; arguing performance in the abstract is one thing, but if twitter is saying ruby and rails are slow(er) there's something to that.
It still seems like a good trade off if rails makes you more productive and you've got to get to twitter's size to feel it.
- ashu 20y agoi think DHH's opinion is fair. without profiling, one really doesn't know what the hell is happening. and by being "slower", i just don't know what the comparison point is. sure, ruby is slower as a language - but for the complete application stack you'd need to compare the performance of django or cake to rails _for the same_ or relatively similar apps. only then, meaningful numbers will emerge regarding where the real difficulty lies.
- aston 20y agoThere's only so much to that productivity argument. I suspect the time it takes to make big changes to the Rails stack for performance sake far exceeds the relatively small savings in initial development time. According to Compete, Twitter's not that big [0]. [0]http://snapshot.compete.com/twitter.com+techcrunch.com?metric=uv http://snapshot.compete.com/twitter.com+techcrunch.com?metric=uv
- brett 20y agoYeah. It's a give and take to be sure. I'd take Twitter's current position any day. But you're right they're still in a position to stay ahead of competition and net productivity of development and scaling has to be considered. Worth noting Twitter's audience is using it a lot differently than Techcrunch's is, so relative audience size is not totally meaningful.

- nickb 20y agoMost of the people I know don't use their web interface to post. They either use AOL IM or most likely SMS through heir cell. That's why twitter.com's number are probably way off.
