Methods for Improving the Performance of A .Net Application Used in a Duplicate Searcher Program

This will be an old-school performance talk.

In this talk, I will share my experience of improving the performance of .NET applications and the techniques I've used to develop and optimize my duplicate file search program for Windows.

In this talk, I will introduce you to:

• Algorithmic optimizations when searching for duplicates.
• Low-level optimizations for comparing data in memory (with examples of disassembled code).
• Choosing the optimal hashing algorithm.
• Optimizations when reading data from SSD and HDD in multiple streams.
• Methods to increase memory usage efficiency and reduce GC pressure.
• Hard links and symlinks in NTFS.
