ImageX and using window imaging from C++

[EDN Admin]

<p style="margin:0cm 0cm 0pt <span style="font-size:small <span style="font-family:Calibri Hi Forum,
<p style="margin:0cm 0cm 0pt <span style="font-size:small; font-family:Calibri
<p style="margin:0cm 0cm 0pt <span style="font-size:small <span style="font-family:Calibri I am attempting to using Windows Imaging API from my own program to restore an image.<span style="

<p style="margin:0cm 0cm 0pt <span style="font-size:small; font-family:Calibri
<p style="margin:0cm 0cm 0pt <span style="font-size:small <span style="font-family:Calibri To restore an example image ImageX can do this in 3min 25sec.<span style="
However from my code I get a total restore time of 9min 50sec.
<p style="margin:0cm 0cm 0pt <span style="font-size:small; font-family:Calibri
<p style="margin:0cm 0cm 0pt <span style="font-size:small <span style="font-family:Calibri I have captured some time information from the WIM calls and the attached program spend 3min 18sec in the WIMCreateFile and 6 min 41 sec in WIMApplyImage.
<p style="margin:0cm 0cm 0pt <span style="font-size:small; font-family:Calibri
<p style="margin:0cm 0cm 0pt <span style="font-size:small <span style="font-family:Calibri Does anyone know how imageX does the restore to achieve the times it gets?
