Hi all,

I have written an application in c# and was surprised with the speed.

I want to know how I can increase the speed of the application???

For example:

  • use generic

  • use 'for loop' instead of 'foreach'

  • use StringBuilder

  • use threading

But, the speed of my application is still very slow??

<pre lang="cs">//***********************************************
       void FillType()
           objType = new BL.BL.Type();
           cmbType.DataSource = objType.GetType();
           cmbType.DisplayMember = "TypeName";
           cmbType.ValueMember = "TypeID_FK";
       void FillLanguage()
           objLanguage = new BL.BL.Language();
           cmbLanguage.DataSource = objLanguage.GetLanguage();
           cmbLanguage.DisplayMember = "LanguageName";
           cmbLanguage.ValueMember = "LanguageID_FK";
       void FillDocument()
           dgvDocument.AutoGenerateColumns = false;
           bsDocument = new BindingSource();
           objDocument=new BL.BL.Document();
           bsDocument.DataSource = objDocument.GetDocument();
           dgvDocument.DataSource = bsDocument;

 private void frm_ListDocument_Load(object sender, EventArgs e)

Slow app = slow code
1. What kind of program are you working on?
2. Post the code.

I agree, you'll have to post some code...

Solution 2

You'll have to profile your application to analyze where most of the time is spent in your code. Visual Studio has a profiler on board I think, but there also many good ones out in the wild:

  1. Yourkit[^]
  2. JetBrains[^]
  3. RedGate ANTS[^]
  4. EQUATEC[^]

Google for "Free .NET Profiler" and I'm sure you can come up with a couple of free ones yourself.

Profiling code performance will pinpoint the bottlenecks in your application and you'll have to analyze what kind of tuning mechanisms could be applied.

Cheers and happy profiling!
