memory write takes more time

Hi,

We recently migrated the server from windows 2008 r2 to windows 2012 r2. We are using ICSharpCode.SharpZipLib.Zip dll to compress the files.

ZipOutputStream.write (highlighted line) used to convert the bytes as file in the zip file. But it takes more time in the new server. I am unaware whether it a memory related issue or unable to find the cause of the issue.

We didn't faced this problem in the existing server. Please help.

Dim fs As FileStream

Dim buf As Byte()

Dim zs As New ZipOutputStream(File.Create(OutputZipFilePath))

If sPass IsNot Nothing AndAlso sPass <> [String].Empty Then

zs.Password = sPass

End If

zs.SetLevel(9)

Dim ze As ZipEntry

Dim sFile As String

For Each sFile In ar

ze = New ZipEntry(sFile.Remove(0, inputFolder.Length))

Dim fi As New FileInfo(sFile)

ze.DateTime = fi.LastWriteTime

zs.PutNextEntry(ze)

If Not sFile.EndsWith("/") Then

fs = File.OpenRead(sFile)

buf = New Byte(CType(fs.Length, Integer) - 1) {}

fs.Read(buf, 0, buf.Length)

zs.Write(buf, 0, buf.Length)

fs.Close()

End If

zs.Finish()

zs.Close()

Thanks,
