    How to set the fill factor values ​​are not a formula or concept can be accurately set. While the fill factor can reduce the paged when an update or insert, but because more pages, so reducing the query performance and take up more disk space. How do I set this value trade-off required to use depending on the situation Look.

    For specific circumstances according to the ratio of read table of view, I think I am here give suitable values:

    1. When the write ratio greater than 100: 1, do not set the fill factor of 100% fill

    2. When the number of read write times greater than, 50% -70% filler provided

    3. When the reader is located between the filling ratio of 80% -90%

    The above data is only my opinion, specific data set should be tested to find the optimal depending on the circumstances.
