Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

you should keep CLR only when TSql does not offer equivalent features
Normally no, unless the computation is very involved and complex.  It is it all data collection, or even mostly data collection, then the various algorithms in SQL Server with the help of indexes and statistics will be faster.

It depends.

As cyberkwiki noted, CLR is very CPU-intensive functions and procedures that feature complex logic.  It should be noted though that using CLR allows you to use the .NET base class libraries which is not available with t-sql.
