Using nobarrier really is a bad idea in general as it does not
actually provides any transactional guarantee.  But if you're the kind
of person that would use it anyway please upgrade to a 2.6.35-rc kernel
and use the "delaylog" mount option, which will uses a new logging
mechanism that will get you much better delete performance.  It's still
experimental, but it's defintively not any worse than using nobarrier.
