To achieve low and predictable latency, it is crucial to fine-tune applications to their environment. Leveraging our decades of experience in OS tuning, Chronicle has distilled these insights into a product which can help optimise Linux-based environments for best performance, with improved latency and reduced jitter.

Chronicle Tune is an integrated package to set up and manage the low-level tuning of Linux hosts. The package is designed to be simple to install and configure, while providing powerful CPU isolation and power management, together with a complementary range of tuned kernel and system parameters. Importantly, the kernel tuning is maintained in lock-step with changes to the CPU isolation configuration.

Simple to install and configure, Chronicle Tune integrates the following:

• CPU isolation, for low-latency, low-jitter tasks
• Transparent control of CPU power management
• Per-thread scheduling using standard calls (eg taskset, sched_setaffinity)
• IRQ management
• Whole-system optimisation, including SSD, disk, memory, and network
