Always useful. Actually, I just fielded on IRC a report of poor I/O utilization with XFS during checkpointing. Not sure if the problem is XFS or PostgreSQL, but the fact that XFS (alone among filesystems) does its own cache management instead of using the kernel cache makes me suspicious. -- -Josh Berkus Aglio Database Solutions San Francisco ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
