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

Changes can be applied dynamically, eg according to a schedule or in response to changing load Correctly tuned systems can not only yield better performance, but also improve efficiencies by more effectively utilising available resources, and matching power demands to load. Depending on your workload and scale, Chronicle Tune can help you extract better performance, and by using available resources more efficiently, has the potential to also reduce hardware costs.
