Stackable Cryptographic File Systems have been adopted as one of the dominant solutions to transparently improve data security. However, how to reduce the performance degradation induced by encryption-operations is still an open problem. To solve the performance degradation problem, Load-aware Adaptive Cache Management (LACM) scheme is proposed, which utilizes a load-aware dynamic scheduling strategy to improve cache efficiency from two aspects: load-aware redundancy elimination and non-redundant cache conversion. Experimental results show that the proposed solution can provide 20.03%~34.39% latency decrease, and supply 12.82%~34.77% performance improvement for application-level workloads. LACM can also be easily adapted to other stackable cryptographic/compressed file systems, such as NCryptfs, stackable compress file system and etc.
