Excluding warehousing setups, where XFS might give some benefit, any modern file system on Linux should perform OK. I'd use what I'm comfortable with. In case your data set fits in RAM, it will stay in OS buffers all the time anyway. My choice is XFS, but I wouldn't recommend XFS to anyone unsure to what FS to use. There is far to much someone new XFS can do wrong. jose fuenmayor wrote: > Hi all, i need to install a database in postgres with high reading rates, > which is the best file system to do that , I am working on linux. > thanks in advance !!!! -- Best regards, Hannes Dorbath
