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.
