| Performance and scalability in .Net (2 replies, VIP) |
| microsoft.public.dotnet.framework.performance |
| As a VB Windows DNA developer I've been used to hosting my COM objects in MTS, making them stateless, and using .SetComplete/.SetAbort, etc. to increase performance and scalability. With VB.net objects not requiring COM or MTS I am wondering what do I need to do to make my objects perform well and scale other than the usual things of getting resources as late as possible/releasing them as soon as ... |

| Application memory footprint (3 replies) |
| microsoft.public.dotnet.framework.performance |
| I was wondering if anyone could tell me why a hello world program takes up 9mb's of memory. I was also trying a rewrite of a program which I did in vb 6.0, which ran using 3.5mb's of memory. I have started the rewrite in C# and am about 1/7th of the way through. The application is already at 18mb's! Is this what I am going to expect all apps to be like and am I going to be stuck with a bloated app... |

| "Statefull" objects - page scope - performance impact ? (2 replies) |
| microsoft.public.dotnet.framework.performance |
| Hi I'm just wondering, is it possible to use statefull objects in C# and still get good performance on you webapplication. I mean instead of using a method that gets all data from the database into a list of variables, example taken from the IBuySpy portal: MyList.DataSource cart.GetItems(cartId); I would like to do: cart.GetItems(cartId); MyList.DataSource cart.Items So that the Items in the shop... |

| VS.NET IDE Startup Performance ? (11 replies, VIP) |
| microsoft.public.dotnet.framework.performance |
| I work on IDE/design time performance, and we'd like to solicit some feedback from your experiences. There are a lot of areas within design time performance (start running with the debugger, project build, project load, etc.), but my team primarily focused on the startup time of VS.NET. We did a lot of work to improve the startup for B2, and we have even more ideas from recent work we've done. Obv... |

| Dotnet Regex (3 replies) |
| microsoft.public.dotnet.framework.performance |
| Hi I've a *big* problem. The .Net beta Regex class is twice slower (on a 35kB string) than the VBS 5.5 one's. And when I remove the RegexOptions.Compiled flag it's 2.5 times slower. Any information about that ? It's very handicapping for me because I'm trying to migrate one of our service to .Net and it's much slower than ASP because of that... Thanks.. |

| Windows Forms performance in C# with irregular edges and regions (2 replies) |
| microsoft.public.dotnet.framework.performance |
| We've got a number of forms in our app, all with irregular shaped borders (all very curvey). We use clipping regions (via Control.Region property). Our problem is that this is very, very slow performing, and has a few artifacts when moving the form around the screen. When dragged "semi" quickly on a 800MHz PII/W2k desktop, the form appears to move WITHIN the current forms's own clipping region, le... |

| XPathDocument is slow. (5 replies) |
| microsoft.public.dotnet.framework.performance |
| I'm loading a ~500K xml document into the XPathDocument object, and it takes about 2 seconds to load. Example : XPathDocument doc new XPathDocument("c:\\xml\\xmlfile.xml"); I'm pretty sure that the XPathDocument is the culprit. When I load the same document into a string, it's much faster. This is pretty fast : StreamReader sr File.OpenText("c:\\xml\\xmlfile.xml"); String input sr.ReadToEnd(); I r... |

| ViewState on server storage? (7 replies) |

| Is there a possible way to keep the ViewState data on the webserver with just a referencing ID in the posted page? I ask this, because our ViewState is becoming quite large and often unnecessary to send to browser and back (on postback). Storing in Session is not an option. Any ideas? Bas Kroes |

| Trivial note... (6 replies) |
| microsoft.public.dotnet.framework.performance |
| FYI We have a unit test that executes a simple no op spin delay in between some methods. The test just checks to ensure that a "LastModified" log field gets updated and asserts when the timestamps don't change. dt1 DoTimeStampMethod(); for(int i 0; i 300l i ) {} dt2 DoTimeStampMethod(); Assert(dt1, dt2); With Beta1 we found a 300 count loop was sufficient to allow at least 1 second to elapse betwe... |
