This is incorrect. Ext2 is strictly standards compliant here. Sendmail at least used to make totally bogus assumptions about synchronous directory updating. I'm suprised that you might not have fixed such code. (Perhaps you have - I run exim because I want fast efficient mail handling and a human readable configuration) > EXT3 will have the same set of problems, infact I was just doing studies Also incorrect. See the documentation. Ext3 also follows the posix/sus requirements and allows you to select additional ordering guarantees As to reiserfs being very fast for very small files. It was certainly designed to be , and Namesys are smart people.
