      Just in case you've never tried an AWS Lambda function written in GoLang, you absolutely should: https://aws.amazon.com/blogs/compute/announcing-go-support-for-aws-lambda/ … It's fast. I mean really fast.

      Faster than js in terms of start-up time?

      I think @hichaelmart has done some comparison

          It wasn't faster for cold boots. In fact, Node 0.10 was the fastest in my testing – because the min binary size in Go is around 8MB vs a few bytes in Node – but tbh it's a bit of a wash. The Go runtime cheats with its reporting, amortizes startup (good for consumers!)

          There may have been some AWS Lambda changes since you did that. Node 0.10 was a while ago.

          Should have clarified – this was using the Node.js 0.10 binary on a Go runtime Lambda. The Node script starts a socket server and speaks Gob to the Lambda controller.

          A Rust binary was even faster actually (because it was 474kb vs 8MB for Go). Bit of discussion about cold start time here:https://twitter.com/hichaelmart/status/953499155011461121 …

          Ok, so after a few hundred measurements, the avg cold start time for Node.js v8.9.4 bundled as a Go Lambda is 534ms (min 326ms, max 1372ms). Sounds not ideal huh? Well, it gets interesting... Avg cold start for a simple Go fn is: 175ms (min 112ms, max 252ms). Better! However...

          I'm really only talking about the supported Go in Lambda rather than anything else. A warm Go Lambda function can run in less than 1ms (YMMV depending on function of course)

          Sure, but @JoeEmison was asking about startup time (which I assume means cold start time). Warm is fast, for sure 👍

          There's some more comparisons here: https://twitter.com/fsenart/status/962070727330377735 … – 95th percentile isn't that different. Problem is they don't account for time outside the "container" – ie, mounting /var/task – where Go's 8MB minimum hurts it. Need to measure from the API really.

          Stumbled upon https://twitter.com/hichaelmart/status/958089800250216453 … I tried to measure the "cold start" time of #AWSLambda as precisely as possible to figure out the benefits of using the new #Golang runtime. TL;DR: the new #Golang runtime is fantastic. pic.twitter.com/1wcQmP9YW7
