Exported PDFs are too big in file size.

I usually export Mathematica plots to PDF format. I don't like bitmap formats. The problem is the file size. Most of the 3D graphics on Mathematica 6 are exported to PDF files as large as several megabytes (even several tens MB sometimes). For example, this simple 3D graphics ContourPlot3D[ Exp[-(x^2 + y^2 + z^2)/2], {x, 0, 2}, {y, 0, 2}, {z, 0, 2}, Mesh -> None] generates a PDF as large as 3.7 MB!! With Mathematica 5, the file size was reasonable. Is there something I'm missing with Mathematica 6? Thanks in advance for any help. mahn-soo
