Comments on: String vs StringBuilder for the .NET Concatenation Performance Championship http://blog.briandicroce.com/2008/02/04/stringbuilder-vs-string-performance-in-net/ On the infinite search for the silver bullet...

I am making an app and needed to preprocess a 6GB text log. It had to be output back to a file about 250 MB in size. Using Stringbuilder instead of Strings cut down the time about 10 times.

Many websites that produce dynamicaly created html with string concatenation (i.e a menu-trees etc) and has a visitor load of a couple of thousands every day may cause the webserver to freeze entirely for minutes before the garbage collector manages to clean out all old string objects. These hickups can be avoided by using a stringbuilder object instead (which in size would be 1/4 of your string example when disposed). This is performance at another level; not just "runtime" performance... Mike; using your above code will produce the following crap for the garbage collector to handle:

“foofoofoo1foofoo1foo2foofoo1foo2foo3foofoo1foo2foo3foo4″

Second, you are wrong. do this: s += "foo" + "foo1" + "foo2" + "foo3" + "foo4"; And see what IL code is executed. We've done the timings too and never use StringBuilder for anything what so ever .... First, you really should correct the mistake in the opening line of your post. Second, you are wrong.

do this:

s += “foo” + “foo1″ + “foo2″ + “foo3″ + “foo4″;

And see what IL code is executed. We’ve done the timings too and never use StringBuilder for anything what so ever ….
