Now I want to implement an algorithm on VSSIM because the latency management of VSSIM is very close to that of a real SSD, so I wanted to know the overhead of this algorithm at VSSIM, which is to know how much overhead this algorithm brings to SSDs, not QEMU Overhead. Such as how many SSD CPU clock cycles the algorithm spends, and how much memory the SSD consumes. I would like to know whether the solution to these problems is whether VSSIM has been implemented or tested through the tools that come with Linux.
Last,in your paper, the total overhead = VSSIM Overhead + Latency of NAND Operarion. How do you understand this VSSIM Overhead?
Thank you for your answer.
