A multi-language offering We’re excited to announce that Chronicle Queue Enterprise is now available in multiple programming languages to ensure maximum user flexibility and…
How to Optimise CPU Performance Through Isolation and System Tuning
What are the challenges of tuning your CPU and system for optimal performance with Linux, and how does Chronicle Tune address them? CPU isolation…
Global Bank Case Study
Building Custom Solutions vs. Buy-and-Build Software
The Challenges of Building a FIX Engine The first day I was introduced to FIX was when I worked at an investment bank in…
UOB Case Study
This tutorial delves into how to use the Chronicle FIX UI, which helps you to add, edit, delete and manage FIX sessions.
Peter Lawrey explores object allocation and how it could be hurting vertical scalability.
How to use Chronicle’s free FIX parser to help decode and read FIX messages
Webinar | Java is Very Fast
Peter Lawrey presents webinar based on his remarkably popular article, ‘Java is Very Fast if You don’t Create too Many Objects’.
Unique Identifiers Based on Timestamps in Distributed Applications
At Chronicle we build applications that must process very high numbers of events with minimum latency. Generating unique IDs for these events using the…
This video follows on from the account balancer example, and in this tutorial we demonstrate how to run Chronicle Services with Docker.
This video is a follow on from the video on Chronicle’s Services Testing Framework, and looks at how Chronicle Services can send DTOs as well as how custom setup data can be added to your configuration file and your YamlTester tests.
Java is Very Fast, If You Don’t Create Many Objects
This article looks at a benchmark passing events over TCP/IP at 4 billion events per minute using the net.openhft.chronicle.wire.channel package in Chronicle Wire and…
This video follows on from the previous video and goes into more detail on the Chronicle Testing Framework.
This video demonstrates a simple example of Chronicle’s Microservices Framework and shows how to send events between two services.
Monitoring Event Loops for Blockages
Chronicle’s open source Chronicle Threads library has a little known feature which is one of the first tools I get from my bag if a…
This tutorial provides a simple example for how to send events and make method calls from one java process to another, using Chronicle Queue as an interprocess communication transport.
Monitoring Chronicle Services
Chronicle Services is a framework for building Event-driven microservices. Microservices built with Chronicle Services are efficient, easy to build, test, and maintain. Equally important…
Dedicated compute optimised instances deliver high performance for compute-bound applications in the cloud. They are, therefore, ideal for low latency applications like Chronicle’s software….
Using Pausers in Event Loops
Typically in low-latency development, a trade-off must be made between minimising latency and avoiding excessive CPU utilisation. This article explores how Chronicle’s Pausers can…
