dotnet performance : Performance issues on different servers.
Hi!
We have a strange problem that we've been trying to solve for some days. We have an application where we have our own custom objects filled with data. We're doing a lot of looping / removing and creating of objects in a specific function. When I run this on my laptop it takes about 1,7 seconds to do the whole operations (it's about 4500 objects filled with data). When I do it on my customers computers this takes a lot longer time. I'm not doing database-queries, communication with other components or anything. It's pure dataprocessing with my own classes. The results are as follows: My computer (1,7 seconds): Laptop Pentium M - 1600 Mhz 1 Gb RAM Windows XP Pro My friends computer (1,8 seconds): Laptop Pentium 4 - 2,66 Ghz 512 Mb RAM Windows XP Pro My customers test-server(12,3 seconds): Server Pentium III - 800 Mhz 1 Gb RAM Windows 2003 Server My customers production-server (5,4 seconds): Server Xeon 2 x 2.4 Ghz 2,2 Gb RAM Windows 2003 Server My customers laptop (6,1 seconds): Laptop Pentium 4 - 2 Ghz 512 Mb RAM Windows XP Pro May there be any security-settings? The only big difference between my and my friends computers are that we are in a workgroup while the customer-computers are in a domain. Are there any other security-settings or anything that my customer may have that affects the performance of our application? Regards Thomas Pettersen / SKUM
did you run a profiler on the app?
I heard Compuware has one for free (haven't used it yet myself for C#, but I like their older version for C++) [quoted text, click to view] Thomas Pettersen wrote:

Hi!
Thanks you. Now I've run this application, but can't see anything special. :) Thomas [quoted text, click to view] "Uri Dor" <replace_yu_ar_eye@mivzak.com> wrote in message news:%23ky3d8kEEHA.3372@TK2MSFTNGP10.phx.gbl... > did you run a profiler on the app? > I heard Compuware has one for free (haven't used it yet myself for C#, > but I like their older version for C++) > > Thomas Pettersen wrote: > > > Hi! > > > > We have a strange problem that we've been trying to solve for some days. > > > > We have an application where we have our own custom objects filled with > > data.

Hi!
I'm only looping through my own objects, removing and adding objects.

Are you doing any form of authentication? Might be that authenticating
against a domain is taking the time whereas the workgroup is local to the machine.

Hi!
I figured out this problem myself. The reason was that I was using some commands like: IsNumeric and cInt. This commands does a lookup in the registry. Our customers computers are on a big domain(s) with a lot of users, and it seems like there is a delay between the application and the registry.Or they have some kind of security-options on the registry on their computers so the delay will still be there. I solved it using Integer.Parse(String, somekindofglobalconfig.none) and char.Isnumeric(string, position) instead. It's easy to check with this code: Public Sub Test() Dim dblStart As Double Dim dblEnd As Double Dim i As Integer Dim blnValue As Boolean dblStart = Microsoft.VisualBasic.Timer For i = 0 To 3000000 blnValue = IsNumeric("1000") Next i dblEnd = Microsoft.VisualBasic.Timer msgBox("Result: " & dblEnd - dblStart) End Sub :) Thomas [quoted text, click to view] "Thomas Pettersen" <thomas@skum.no> wrote in message news:u3de4zkEEHA.3980@TK2MSFTNGP09.phx.gbl... > Hi! > > We have a strange problem that we've been trying to solve for some days. > > We have an application where we have our own custom objects filled with > data.
