What is the best value for fill factor in SQL Server?

What is a good fill factor in SQL Server?

What is meant by fill factor?

The Fill Factor (FF) is essentially a measure of quality of the solar cell. It is calculated by comparing the maximum power to the theoretical power that would be output at both the open circuit voltage and short circuit current together.

Rebuild : rebuild drops the existing index and recreates again. Reorganise : reorganize physically arrange the leaf nodes of the index. If index fragmentation shows above 40%.

When should I rebuild indexes SQL Server?

There’s a general consensus that you should reorganize (“defragment”) your indices as soon as index fragmentation reaches more than 5 (sometimes 10%), and you should rebuild them completely when it goes beyond 30% (at least that’s the numbers I’ve heard advocated in a lot of places).

The “fill factor”, more commonly known by its abbreviation “FF”, is a parameter which, in conjunction with Voc and Isc, determines the maximum power from a solar cell. The FF is defined as the ratio of the maximum power from the solar cell to the product of Voc and Isc so that: F F = P M P V O C × I S C.

Which is faster sorting or indexing?
