Does anyone know of a resource that tells the relative speed of comparable functions (and classes) in .NET. e.g. The stringbuilder class is MUCH faster than string1 & string2. I'm wondering about how fast some of the functions and classes actually execute. e.g. Select Case vs. If Then and arrays vs. collections, etc. etc. etc. ------------- http://renegademinds.com/" rel="nofollow - Renegade Minds - Guitar Software http://renegademinds.com/Default.aspx?tabid=65" rel="nofollow - Slow Down Music |

Not hard to do your own tests. Use the built in .Net performance thingy which measures requests/second. ------------- There have been many, many posts made throughout the world... This was one of them. |

I saw a few on msdn which compares datagrid vs. datalist vs. repeater do a search there I am sure MS has tons on that. ------------- http://baumannphoto.com" rel="nofollow - Blog | http://mpgtracker.com" rel="nofollow - MPG Tracker |

I didn't see anything at MSDN. I'll check back on it though. ------------- http://renegademinds.com/" rel="nofollow - Renegade Minds - Guitar Software http://renegademinds.com/Default.aspx?tabid=65" rel="nofollow - Slow Down Music |

This is the performance article I talked about on MSDN, I am sure there are more then this one: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnaspp/html/aspnet-whenusedatawebcontrols.asp - http://msdn.microsoft.com/library/default.asp?url=/library/e n-us/dnaspp/html/aspnet-whenusedatawebcontrols.asp ------------- http://baumannphoto.com" rel="nofollow - Blog | http://mpgtracker.com" rel="nofollow - MPG Tracker |

This is one article that has several issues covered: %20http://www.fawcette.com/vsm/2002_08/magazine/features/bale%20na/default.aspx - http://www.fawcette.com/vsm/2002_08/magazine/features/bale na/default.aspx The title is http://www.fawcette.com/vsm/2002_08/magazine/features/balena/default.aspx - Speed Up Your VB.NET Code It also covers the StringBuilder method along with the reasons. Thanks Michael. I'll read up on that MSDN article. P.S. There seems to be a lot of link spamming happening in the forums lately... ------------- http://renegademinds.com/" rel="nofollow - Renegade Minds - Guitar Software http://renegademinds.com/Default.aspx?tabid=65" rel="nofollow - Slow Down Music |

using string concatenation was an error either in VB6. There was a pattern to use mid function to obtain a class similar to .NET stringbuilder. My tests reported 40% better performance with this patter instead of string concatenation.

It really depends on what you are doing with the StringBuilder. In one small app processing a small file, I sped it up by over 200x by changing to StringBuilder. In another instance, the stringbuilder could do it, but string concatenation simply could not do it at all, at least before my patience ran out. There I was working with strings a few MB in size. I know that if I were using larger files, the speed difference would be larger. So obviously we aren't dealing with a strictly static performance improvement. It would be nice to know the equation that would tell us exactly what the performance improvement 'curve' is.
