One winter day, instead of finding a gift under the Christmas tree, we discovered that our system had hit its maximum data insert rate. Spoiler: in the next few weeks we managed to boost the insert limit from 2,000 to over 22,000 operations per second. I’ll walk you through how we managed to prepare for the peak load — without dramatically changing the architecture. I’ll also show performance bottlenecks that can hide in the database.

We’ll look at Hot Last Page Contention using MS SQL as an example — though this is a well-known issue in many relational databases. This story will be interesting to anyone fighting for every extra thousand inserts per second — or for those who simply enjoy a good IT thriller.

Modern CPUs are beasts of performance. Are you sure your Python program uses significant part of this power? Or even your C program?

This talk gives you a glimpse of what has changed in CPUs in the last 30 years, and why it's important to software engineer's day-to-day work and month-to-month AWS bill.

SecOps is a hot topic these days, so we decided to have a chat with CyberSift and Altenar experts on how popular open source tools like ClickHouse, NiFi, Elasticsearch and Grafana can be used to build SIEM (Security Information and Event Management) systems. David and Keith will share lessons learned from building a SIEM, and Nikolay will host the discussion.
