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...

Alina Yurenko Developer Advocate for GraalVM @Oracle

JIT vs AOT Performance With GraalVM

What are the goals you have for the talk?

I want to offer an additional point of view on performance. Performance is something people often talk about but often focus on one or two metrics, and there might be more ways to look at it, and additional opportunities to optimize. We will go through some additional metrics, discuss how they are connected, and how you can optimize...

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...

You Can Build a World-Class Search Engine in .NET

What have you been up to since last time you were at QCon?

I still work a lot on performance and detail .NET stuff but my focus switched towards teaching others and getting other people on board with high performance .NET and techniques that we use to debug and and to improve performance.

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...
