It's my experience too that XFS often performs badly with the default
mkfs/mount options, especially for metadata intensive workloads. The
drawback is that it eats memory. I've been thinking about making it
set the bigger mount option by default based on the available physical
memory; this would probably help a lot of users.
iirc one drawback is that it eats from the vmalloc area which is only 64MB
by default on 32bit. But still should not be that big an issue. On 64bit
it's not an issue at all of course.
Of course the log size cannot be changed this way, but perhaps the default
in mkfs is just too small for today's disk sizes?
