Hi all,
after installing Service Pack 1 for .NET Framework 1.1 my Application slow
down - using 10x execution time for some calculations.

This Problem occurs on more than one PC and is repeatable.
After deinstalling .NET Framework and reinstalling without Service Pack ->
the application runs 10 x faster!

The code-lines executed in this time are only calculations in DataSets /
DataRows / Selects / Filters / Sorts and a lot of new - Operations, all in
Memory. The Data Sets are fetched from an Oracle Database and are stored 100%
in RAM this time.

any ideas welcome ..?
thanks in advance

During last night i limited the scope of the problem:

The slow code is a recursive function, calling "Select" on a DataSet. The
result is parsed in a "foreach" loop.
Additionally there are some "Convert.ToBoolean" and
"Convert.ToInt32" from type object
(like Convert.ToInt32( mydataset["COLUMNNAME"] ) )

I'm still without idea
-please help-
