Elevator Pitch (300 chars)

How many requests per second does your application serve? Are you sure? This talk covers the basics of load testing Go applications with off the shelf tools. You will leave with practical knowledge to test your own applications. Stop lying about performance.

Description

Stop lying about the performance of your application! Learn about load testing. When working at a prior startup a customer asked if we could handle 10,000 to 20,000 requests per second. Could we? Sure. Maybe. Well, probably.

It turns out we could handle about 180 requests per second. The customer was OK with caching results to reach their goal but our Go application bottlenecked our progress. Before we made any changes we measured. And once we identified potential solutions we could benchmark as we made changes. We could confirm what did and did not work.

About

I need to create tile sets that will work with Cesium Widget from local disk.

Steps

Use TileMill https://tilemill-project.github.io/tilemill/ to setup a map and export it as .mbtiles (sqlite).

Use mbutil https://github.com/mapbox/mbutil to convert from sqlite to PNGs on disk.

}

for k, v in things.items():
    pass

print("k leaked: " + k)
