Windows 10: Multithreading Performance issue in windows 10

Hi,

I have a program developed in VB.Net a specific operation in the application uses memory(arrays) to store the details. We use threading in the application.

The application was running perfectly around 15 mins in Windows 7 OS. The problem started when we have migrated into new OS i.e. Windows 10.

It takes around 3 hours to complete the same operation which looks abnormal in any kind of application.

Can any one help me out this to sort this down?

Sys Config: Win'10 Intel(R) Core(TM) i5-7500T CPU @ 2.70GHz 2.71GHz, 8GB RAM, 4 Core

Win'7 Intel(R) Core(TM) i3 CPU 550 @ 3.20GHz 3.20GHz, 4GB RAM, 4 Core.

The code which taking more time to get execute is added here:


Private Sub ComputeAverageMark(ByVal ExamAndMarkDS As DataSet, ByRef ErrorDetailsObj As ErrorDetails)
Try
Dim ExamValue As New Exam
Dim ExamForAnalysisValue As New ExamForAnalysis
Dim ExamDT As New DataTable
Dim ExamListArgsValue As ExamListArgs
Dim MarkDT As New DataTable
Dim count As Integer = 0
Dim ExamListArgsList As New List(Of ExamListArgs)

ExamDT = ExamAndMarkDS.Tables(0)
MarkDT = ExamAndMarkDS.Tables(2)

Dim MarkHashTable As Hashtable = GetMarkHashTable(MarkDT)

For Each ExamDR As DataRow In ExamDT.Rows

count = count + 1
If MarkHashTable.ContainsKey(ExamDR.Item("ExamName")) Then
MarkDT = MarkHashTable(ExamDR.Item("ExamName"))
Else
MarkDT = MarkDT.Clone
End If

ExamListArgsValue = New ExamListArgs(ExamDR, False, MarkDT, True, 1, ErrorDetailsObj)

ExamListArgsList.Add(ExamListArgsValue)

If count >= 100 Then
Dim paralleOptions As New ParallelOptions
paralleOptions.MaxDegreeOfParallelism = 4

Parallel.ForEach(ExamListArgsList.ToArray, paralleOptions, Sub(ExamListArgs)
ComputeAverageMark(ExamListArgs)
End Sub)
ExamListArgsList.Clear()
count = 0
End If

Next

If count > 0 AndAlso count < 100 Then
Dim paralleOptions As New ParallelOptions
paralleOptions.MaxDegreeOfParallelism = 4
Parallel.ForEach(ExamListArgsList.ToArray, paralleOptions, Sub(ExamListArgs)
ComputeAverageMark(ExamListArgs)
End Sub)
End If

Catch ex As Exception
Throw ex
End Try
End Sub


Thanks in advance

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
