This might in turn perturb load-balancing of real-time tasks. -6. The LB_BIAS scheduler feature is disabled by adaptive ticks. - Although improvements are expected over time, adaptive ticks is quite useful for many types of real-time and compute-intensive applications. However, the drawbacks listed above mean that adaptive ticks should not
