Hi All gurus, Thanks for your comments. I did few experiments with papervision3D and away3Dlite and found that both were working almost same. it was because of transparency as Peter and Joshua mentioned however I tried to use same transparency and removed obj.material.smooth property and now CPU usage is reduced about 60%.
You can check both results on following links Papervision http://www.riyasatali.com/site/pv/camExp1.html Away3D http://www.riyasatali.com/site/aw/site.html I also want to put your attention to the following site it's in papervision and they are using a lot of pngs http://www.hanazuki.com/cases/ How they managed to handle that? check this out.
