摘要：

An optimized latency model and a write speed adjustment scheme are proposed to accelerate master-slave databases launched on LDPC-induced solid state drives. To the best of our knowledge, no prior work has been published to systematically study the utilization of read/ write latency model on LDPC-induced master-slave databases and the impact of fast write operations on databases reliability. Experimental results show that the proposed MFW-SFR approach outperforms traditional ones with a 57.11% reduction of average read latency time on slave sites and a 33.23% reduction of average write latency time on master sites.
