Hi Jens, In continuation with our previous communication, we have carried out performance comparison among EnhanceIO, bcache and dm-cache. We found that EnhanceIO provides better throughput on zipf workload (with theta=1.2) in comparison to bcache and dm-cache for write through caches. However,

Hi Jens and Kernel Gurus, We are submitting EnhanceIO(TM) caching driver for an inclusion in Linux kernel. It's an enterprise grade caching solution having been validated extensively in-house, in a large number of enterprise installations. It features this distinct property not found in dm-cach
