Concurrency

Question

How does increasing levels of concurrent client requests affect tail latency, throughput, and the success/error rate of sandbox execution?

Independent Variable

The number of concurrent client requests made at a given time

Dependent Variables

p50, p90, p99, and p100 latency measured in ms
throughput measures in requests/second
success rate, measures in % of requests that return a 200

Assumptions about test environment

You have a modern bash shell. My Linux environment shows version 4.4.20(1)-release
hey (https://github.com/rakyll/hey) is available in your PATH
You have compiled sledgert and the empty.wasm.so test workload

TODO

Harden scripts to validate assumptions
Improve error handling in scripts. If sledgrt crashes, this charges forward until it hits a divide by error when attempting to clean data that doesn't exist
