this would basically require creating a zope filesystem, and would have to be ported to each individual system.. yuch.. Not really. This would basically require a symlink from Data.fs to /dev/yourdevice, and a bit of massaging (backup files?) in ZODB.

I can say pretty definately that as much as people want to talk about this, there's no plans anywhere in the future to do this. If someone wants to do this, this is a good community project, but I can think of dozens of other places where huge performance bonuses could be gained before this kind of micro-optimization will ever make an impact. Caching offsets this a huge amount. BTW, my benchmarks on Oracle on raw devices v. file systems shows that on non-RAID that raw is 5-10% faster, but on RAID, it's 2-3x slower... so I don't see this as some huge benefit. Theory and reality rarely are kissing cousins. Chris -- | Christopher Petrilli Python Powered Digital Creations, Inc. | petrilli@digicool.com http://www.digicool.com
