Sydney Lambda Meetup September 2018

About Me Us

Round 1
Round 2

2018 Round 1 Multi Lingual

Round 1 Feedback


  • Lambda Signatures were inconsistent
  • Java had way too much overhead, log4j etc
  • No cold start
  • No detailed metrics on median, p95, p99 etc


  • No actual workload, add downstream service call like DynamoDB or S3
  • .Net Core is fast? That's unpossible!
  • Add other JVM flavours Scala/Kotlin since F# maded it in
  • Add Google Cloud and Azure

Not Doing

  • Not "realistic"! Add universal "realistic" scenarios

Round 1 Results

  1. .Net 2.0 Outperforms
  2. Go and Java is about the same
  3. Consistent Performance between Dynamic vs Static
  4. Go Packages are bigger than Java

Round 2

Including Cold Starts

The Winner

Is You!

The median results are quite consistent between runtimes


But the real benefit of Serverless is in the paradigm shift towards Simplified Operating Model and Focus on Business Value
