Ubuntu native is much faster. It's odd that Wine is so slow.. I wonder why?
That's been my experience, in any case; doing lots of small file operations barely causes any disk activity in Linux, but far more in Windows. Moreover, abruptly cutting power in the middle of that would likely result in far more writes lost on Linux than on Windows.
Doing that IMHO matches real world use much better. If I do a compile and get a power outage I don't care if some object files get lost. If I do an INSERT in a DB I do care a lot but the DB knows that and will fsync before telling me it succeeded. So making sync explicit gives you both great performance and flexibility.
The real world use is someone working on a document, using Save periodically, and expecting whatever was last saved to survive the next outage, not some arbitrarily old version.
In other words, Windows implicitly fsync's often.
