Looks like we have expert help here :-) One very interesting question
would imho be, how do we best preallocate the log files ?
The current method is to prewrite 8k pages to the whole file, since
only writing 1 byte to the end of file triggered the sparse file handling.
This, although usually during off peak times, effectively doubles the writes
for WAL.
