我有两个应用程序,一个通用方法和相同的代码,第一个应用程序是一个32位编译的网站,第二个是64位编译的wcf服务。
这两台机器都是64位: 拉姆6 gb 处理器Intel(R)Xeon(R)CPU E5645 @ 2.40 GHZ
问题是在WCF服务中运行时,同一段代码需要更多时间:
Private Shared Sub AddImageToOutputPDF(ByRef pdfDoc As PdfSharp.Pdf.PdfDocument, ByVal freeImg As FreeImgDLL.freeImage)
Dim page As PdfSharp.Pdf.PdfPage = pdfDoc.AddPage
Dim gfx As PdfSharp.Drawing.XGraphics = PdfSharp.Drawing.XGraphics.FromPdfPage(page)
Dim ts As New TimeSpan
Dim st As New DateTime
Dim en As New DateTime
st = DateTime.Now
If freeImg.verticleDPI = 0 Then
freeImg.EstimateAndSetResolution()
End If
Dim tiffImage As PdfSharp.Drawing.XImage = PdfSharp.Drawing.XImage.FromFreeImage(freeImg)
page.Width = New PdfSharp.Drawing.XUnit((tiffImage.Width / tiffImage.HorizontalResolution) * 72)
page.Height = New PdfSharp.Drawing.XUnit((tiffImage.Height / tiffImage.VerticalResolution) * 72)
gfx.DrawImage(tiffImage, 0, 0, page.Width, page.Height)
en = DateTime.Now
ts = en - st
_log.Debug("Page Operation--- Add Page To Pdf using PdfSharp. ------------------Time in seconds: " + ts.TotalSeconds.ToString)
End Sub
有什么想法吗?
