Is it really true that Lambdas can take 5 minutes to start up? Doesn't that rule them out as useful for things like running a website (instead of just background jobs)? Or does the article mean 5 minutes from the first time you deploy a new one to the time it's available, but after that new lambdas can be spun up in milliseconds to server each request?

No, that is not true. While AWS Lambda has cold-start issues, they can be mitigated.

While AWS continues to improve Lambda performance (it's still early tech), I've started an "Optimization" section in the wiki, detailing how everyone can get better performance out of JAWS.

Further, JAWS is optimized for AWS Lambda performance.

Oh, okay, I must have misread the article then. Sounds good :-)
