This was XFS Achilles heal until the introduction of Dave Chinner's delayed logging patch in 2.6.35. Prior to this XFS was absolutely horrible with metadata intensive workloads including the two you name above. Such metadata workload performance is now on par with EXT3/4 and Reiser. delaylog is a mount option up to 2.6.38 and is the default in 2.6.39.
