JRE installation during OSD

Hi All

I am working on Task Sequence and have a task to install JRE (32 and 64 bit).

.exe file is being used to do the installation, following is the vb script being used. The installation does happen without any issue, but it takes 10-14 minutes. 

set objShell  = CreateObject("WScript.shell")
javaArr = Array("jre-8u321-windows-x64.exe","jre-8u321-windows-i586.exe")

For j = 0 to 1 Step 1
installApp = "cmd /c " & javaArr(j) & " /s /L C:\Windows\Temp\O" & javaArr(j) & "_Install.log"
i = 0
i = objShell.Run(installApp, 1, True)
'Wscript.Echo "Exit Code for " & javaArr(j) & "  : "& (i)
Next

Wscript.Quit(i)
Set objShell = Nothing

I tested the script by executing manually, the installation gets over in 2-3 mins.

Then tried to split the JRE installation with different program for 32 and 64 bit; but improvement. Below is the SMSTS log snippet for the 64bit installation
