[PERFORM] Very important choice

[Lago, Bruno Almeida do]

Hello my friends,   I'd like to know (based on your experience and technical details) which OS is recommended for running PostgreSQL keeping in mind 3 indicators:   1 - Performance (SO, Network and IO) 2 - SO Stability 3 - File System Integrity   Comparisons between Slackware, Gentoo and FreeBSD are welcome.   Which file system has the best performance and integrity: XFS (Linux) or UFS (FreeBSD)? *I've read that UFS is not a journaling FS. Is this right? How much this difference affects performance and integrity?   I don't have experience with FreeBSD so I'd like to know if it is possible to run XFS on FreeBSD 5.3.     Thank you, Bruno Almeida do Lago
