I'm not so sure I would agree with such a blanket generalization. I find NTFS to be very fast, my main complaint is
fragmentationissues...I bet NTFS is better than ext3 at most things (I do agree with you about the cache, thoughO.
I think in very general sense the open source stuff is higher quality but Microsoft benefits from a very tight vertical
integrationof the system. They added ReadFileScatter and WriteFileScatter to the win32 api specifically to make SQL
Serverrun faster and SQL server is indeed very, very good at i/o.
SQL Server keeps a one file database with blocks collected and written asynchronously. It's a very tight system
becausethey have control over every layer of the system.
Know your enemy.
That said, I think transaction based file I/O is 'the way' and if implemented on Reiser4 faster than I/O methodology
thanoffered on windows/ntfs.
