You deploy a custom Web Part named WebPart1 to a SharePoint site.

WebPart1 contains the following code segment. (Line numbers are included for reference only.)

01 protected void Page_Load(object sender, EventArgs e)
02 {
03 SPSite site = null;
04 try
05 {
06 SPSite site = new SPSite(“http://www.contoso.com/default.aspx”);
07 SPWeb web = site.OpenWeb();
08
09 …
10 }
11 catch
12 {
13
14 }
15 finally
16 {
17
18 }
19 }

After you deploy WebPart1, users report that the pages on the site load slowly.

You retract WebPart1 from the site.

Users report that the pages on the site load without delay. You need to modify the code in WebPart1 to prevent the pages from loading slowly.

What should you do?
