Understanding Python Memory at Instagram

Instagram server is one of the biggest Python deployments in the world to support more than 700M active users. At Instagram, the computing parallelism is based on multi-processing instead of threading. Memory utilization becomes critical in such model, i.e., with less memory per process, we are...

NDBench: Benchmarking Microservices at Scale

Netflix runs thousands of microservices to serve more than 100M users everyday. These services are backed by large fleet of data store instances running on the public cloud. It is nearly impossible to predict the traffic patterns imposed by our architecture upon our data stores. We needed a...

Parsing JSON Really Quickly: Lessons Learned

What is the work you're doing today?

I work on software performance from what I call a data engineering point of view. These are the kind of problems that interest me. You start with large volumes of data and processing the data itself is the bottleneck or indexing the data or crunching it or whatever you want to do with the data.

High Resolution Performance Telemetry at Scale

What's the goal of the talk?

We're going to talk about the challenges of measuring performance at scale especially in a distributed microservice architecture. A web request is hundreds of milliseconds. Having a lot of traditional telemetry collection happens at much coarser time scales and a lot of that is due to the cost of aggregation and processing those...

Performance Beyond Throughput:An OpenJ9 Case Study

What is the focus of your work today?

For the past 14 years I've been working on Java JIT compiler development at IBM. However, I am not your typical compiler guy because I don't focus that much on code generator or optimizer. Instead I deal with heuristics that determine what methods to compile, when to compile them and how much to optimize them. With Java, and any other...

Capacity Planning for Crypto Mania

What's the focus of the work that you do today?

Jordan: We’re on the Reliability Team at Coinbase. It was formed in response to the crazy spike of scaling challenges around 2017 with Cryptocurrency. The work is focused on traditional SRE topics of monitoring and instrumentation. We act as consultants for other mostly feature-focused teams. For example, we embed in teams to make...
