We don't know a lot about logfs, so you will really have to make your own comparison. However our general impressions are as follows: 1. In our testing logfs file operations seem to be much slower, see http://osl.sed.hu/wiki/ubifs/index.php/IOzone 2. logfs code base is much smaller i.e. UBIFS has 3-4 times as many lines of code. 3. logfs does not seem to have bad-block handling. 4. logfs does not seem to have wear-leveling. 5. We are not certain how scalable logfs is. We could be wrong about those things - don't flame us if we are. Ask us about UBIFS, not logfs. | ||||||||||||
