This study addresses high system latency and unclear mechanism synergies under memory pressure by conducting ablation experiments based on Linux PSI, zram, and cgroup v2 to evaluate bounded reclamation strategies. The findings reveal that memory optimization benefits are not universally applicable but are instead highly contingent upon foreground workload characteristics and memory access patterns. Specifically, experiments demonstrate that bounded reclamation reduces p99 tail latency for compute-intensive tasks by 6%, yet yields no significant improvement for I/O-bound workloads such as SQLite. By elucidating the differential efficacy boundaries of memory management mechanisms across heterogeneous workloads, this work provides empirical evidence to support fine-grained latency governance in resource-constrained environments.
