In this Tech Talk, Tudor Brindus, a software engineer at Jane Street, shares his expertise on reducing jitter—deviations from mean input processing times—in low-latency systems. Maintaining consistently low jitter in a trading system allows us to offer tighter markets without incurring additional risk. Using a simple memory ping-pong application as a case study, Tudor will walk through how to identify and resolve common sources of jitter caused by both Linux kernel and microarchitectural conditions.
