[Disksim-users] query

[yue]

    Recently I have used the cache function of the disksim, but I have a query about the cachedev function(I want to use the cachedev function). In the valid file of the disksim, when we use the disksim running the single disk(not simpledisk) module(topology 1), the response time is 11.788649, but when use the disksim running the synthcachedev.parv file(topology 2) to complete a disk cache disk structure, the response time is 22.834661, why the response times of topology 2 is large than topology 1, and the difference is so clearly, almost twice. So I want to know where is the cache work, and the using meaning of cache.
   Futhermore I want to know whether the cachedev only support the disk module and not support the simpledisk module.
   Thank you! 
  Best regard!
