Hi,

I am looking for a source (e.g. book) how to improve the performance of C#
applications.

Two words: measure, profile

Once you've isolated the cause of any performance bottlenecks, actually
fixing them is often reasonably straightforward.

Rico Mariani's blog has lots of good tips.

Hi,

You need first to nderstand the best practices in .NET and C#. cause
otherwise, even if you find a bottleneck, how are you going to solve it?
Check Jon Skeet's book. Also in MSDN you will find lot of articles about
what best practices to follow. Like how to better compare strings, string
concatenation, etc

Reimplementing algorithms might help also. For example, the program I am
working on compared hundreds of XML files. There is a master file that
lists names that can occure on other files. Older version used xpath to
search name from the master file and then from the file to be compared.
I put the master file's names to SortedDictionary<string,XmlElement> and
did the same for each file to be compared. Then I used merge, i.e.
walked the names in alphabetical order and each time I found a name in
the compared file that was missing in the master file, reported the
name. The old comparison took about 15 minutes, the new one about 15
seconds.
