Performance of Data View row filter

Dear Folks,
Please clarify me on whether a filter on dataview is a performance
bottle neck. we know that
we cannot apply successive filters to a data view. so the better way is
having the 'And' condition in the
Filter expression. suppose i have some 4 and conditions in my filter
expression what will be its effect on the
performance.
or is there any other way round. if so please let me know the details of it.
Thanks in advance.

Filters can be a drag, but it's impossible to give you a definitive
answer. You have to measure the filters you are using in your
application with the expected load your application will receive to
determine if the performance hit is acceptable or unacceptable.
Does the data underneath the view come from a database query? If so,
one way around the performance problem is to add WHERE or HAVING
clauses to your SQL query - the database is generally much better at
filtering a set of records than .NET is.
