Using a VB script to help speed web pages

I found a article about using workflow to open all pages and then close them every 5 minutes to speed up pages.

i made a vb script that does the same thing and put it in the schedueler to run every 10 minutes.

    Set objIE = CreateObject("InternetExplorer.Application")
    objIE.Visible = 0
    objIE.Navigate "http://localhost/ProcessManager"
    WScript.Sleep 4000
    objIE.Navigate "http://localhost/ProcessManager/Portal/Template100.aspx?PageID=13325f81-69cc-4f49-bce1-48607b96250c"
    WScript.Sleep 4000
    objIE.Navigate "http://localhost/SD.Feeder.TechnicianIncidentForms/composer.aspx"
    WScript.Sleep 4000
    objIE.Navigate "http://localhost/SD.IncidentManagementSimple.EndUserRequest/composer.aspx"
    WScript.Sleep 4000
    objIE.Navigate "http://localhost/SD.Feeder.KnowledgeBase/composer.aspx"
    WScript.Sleep 4000
    objIE.Navigate "http://localhost/SD.Feeder.ProblemCreation/composer.aspx"
    WScript.Sleep 4000
    objIE.Navigate "http://localhost/SD.RequestAccessToNetworkShare/composer.aspx"
    WScript.Sleep 4000
    objIE.Quit

and the pages do open up much faster but is there a way to speed up the parts in the documents. like the "Search Contacts" in advance incident manager?
