OK so am I hearing: XFS is the fastest (but is it the safest?) but does not come on Linux. Ext2 does less work than Ext3 so is fastest among what DOES come with Linux - but if you have a crash that fsck can't fix you're hosed. Ext3 is quite a bit slower if set to be real safe, a wee bit slower if run with standard options which makes it more crash-safe, and much slower if the mount flags are set to metadata journaling but that is much safer as a file system because the metadata journaling is complementary to the PG transactioning. To determine which you want you must choose which one feels to you like the right balance of speed and the setup work you are willing to perform and maintain. Do I have it right? Jeff
