But I don't want to go the Informix/Oracle way where we have so many
tuning options that no one understands them all. I would like us to
find the best options and only give users choices when there is a real
tradeoff.
For example, Tom had a nice fsync test program. Why can't we run that
on various platforms and collect the results, then make a decision on
the best default.
Trying to test the affects of fsync() with a database wrapped around it
really makes for difficult measurement anyway.
