However for larger jpg files, say 150kb it is very slow. I could use some ideas how to improve this.

The StringBuilder ist much faster when concating strings.

Thanks, that did it. It is very fast now. I also got this answer from the delphi newsgroup. This seems somehow to be a worst case scenario, that is not optimized by the compiler.

The C# compiler creates a StringBuilder automatically if you concat more than 3 or 4 strings.
