XFS Isn't faster than EXT3, but it has been documented as being stable.
EXT3 is in a constant state of development, where as XFS has been used
consistantly by large corporations for 3 or 4 years now with good sucess.
I am sorry to hear, however, that you had a problem with XFS. I have seen
nothing but good from it.  However, XFS has been benchmarked (I'll find
the site again) slightly higher than EXT3, ext2 had the highest, but isn't
journaling. limiting it as an FS. However, its not my job to determine
what kernel you people use.  I was simply stating what my experiences
were.  Also note that different versions of your kernel can DRASTICALLY
affect how much performance you gain/lose from a FS up/down-grade.
