Hello,
I know that if Instant File Initialization is enabled, it does not zero out the mdf but ldf file is zeroed out awlays . I was testing few things with this and found that it actually zeros out the ldf file twice. once, while creating it and once, while starting the database, not sure why???
I can see when the database starts, it will read the log but do not understand why it zeros out after starting the database??
Hope it Helps!!
