# From my webinar for Sysdig - Exploring Kubernetes 1.18

# Create A KinD or k3s cluster with no IngressController
# Run `arkade install ingress-nginx` to add IngressNginx to the cluster as your IngressController

# Save and apply all the Kubernetes YAML files below

# Forward the IngressController
# kubectl port-forward ingress-nginx-controller 8080:80

"""Server-side I/O Performance in Python

Based on the article and discussion at:

https://www.toptal.com/back-end/server-side-io-performance-node-php-java-go

The code was posted at:

https://peabody.io/post/server-env-benchmarks/

Is this a fair benchmark?

• I'm comparing the speed of inserting UUIDs into columns which are indexed with btree vs hash
• Want to ensure that I'm measuring both insert queries at their best performance
• Profiled each of them to check whether there is interference by server misconfiguration

Flame graph results

Both were sampled with perf record -F 99 -u postgres -g --call-graph dwarf -- sleep 180
