First let me say that this is not a debate of whether to have autogrowth turned on or off. For this post we are going with it is turned on. So for those of you who use the autogrowth on option as a fail safe, what size do you set your databases to auto grow by in megabytes. I have recently started getting control of my SQL environment and monitoring my amount of free space in my data and log files so that they are not having to auto grow. In the event that one does have to grow, what have you found is the best recommended file size that produces the least amount of impact to your systems. I know that while the file is having to expand that I am taking a performance hit. I have read a few places that have stated 100 MB is good. I have seen recommendations in other spots for 250 MB. We all know that 10% is bad, but what is that good rule of thumb number. I figure instead of reading different blogs and searching across bing and google I would just ask my SSC community what you are doing.
