Thanks for this fun article :) I noticed your serverless function response time is between 2000 to 3000ms, I wonder why and it would be super interesting to have more details about time taken by each step of the process (python proxy / dosbox / qbasic / openwhisk)

Point of comparison, nodejs function executed on AWS Lambda: https://00demo-32387b.appdrag.com/api/Morse?txt=SOS-Test

Thank you!

On a "warm" invocation, almost all the time goes into DOSBox + QBasic.

Not precise measurements but: on my MacBook Pro, running the QBasic interpreter from within DOSBox consistently takes about 1.5 seconds & running DOSBox + QBasic from the shell in "headless" mode takes about 2.4 seconds.

OpenWhisk also gives me the logs of the invocations, which include debug lines produced by DOSBox, and from the timestamps in those I can tell that invocations do typically spend >2s running DOSBox.
