StringBuilder

[cptHotkeys]

Hi, Is the stringbuilder any better\faster at concatenating strings with

sb.Append("TEXT");
sb.Append(",");
sb.Append("Text");

rather than

strText = "Text" + "," + "Text";

I have a very long operation wich concatenates thousands of strings for inserting into a database (14 strings per record), is the string builder class going to provide any performance gains over normal string concatenation?
String handling is the final area for me to get anymore performance gains out of it, I am already running it on a seperate thread. Also if I use SQL CE ( compact edition) will I get anymore performance out of that rather than MS Access?

Thanks...
