Hi, I'm currently evaluating using lvmcache with a local disk as a cache for a slower network attached disk, both of these are SSDs. The default value for `cache_pool_max_chunks` is 1,000,000 and I'm wondering the about the reasoning behind this. Is there degradation if the value is increased or has it not been tested? With the current limit, a larger cache will be fairly inefficient with smaller random reads due to large chunk size being allocated, and the warmup of such a cache would take some time. Thanks
