Shaping usually results in less dropped packets because of its default buffering. Policing can provide about the same drop rate, but the default burst sizes often need to be adjusted. However, shaping also offers the advantage that the bandwidth hog's packets are "metered" into the other traffic, where policing will allow bursts through.
I.e. If available, I would prefer shaping. Unsure how extensive a 6500's shaping features are. Also, generally you can only shape outbound, but you can often police either inbound or outbound.
If your devices support it, it's possible to both police early to control the sender's transmission rate via policing and later manage possible congestion with a shaper or other queuing.
For another approach, if instead of 8 Mbps, 10 Mbps was acceptable, you might also configured Ethernet at 10 Mbps on the source's Ethernet port. (Might even be doable with timed scripts.)
Marwan, yup, I understood what you meant, but from your second post, I presume you didn't realize I didn't see your post until after I had posted mine. I had considered, after seeing yours, adding a postscript acknowledgment of your post to my post, but figured the close post times, 4 minutes, showed what likely happened (i.e. I'm a slow typist).
Another reason I didn't amend my post, I thought there was some value in my suggesting doing the policing on the 6509, rather than later downstream such as your suggestion of policing on the ASA's outside interface.
Of course, it's likely bandwidth is less an issue until you get closer to the WAN bottleneck, but in principle, I'm sure you'll agree that perhaps an (inbound) policer on the 6509 would be even closer to the source, as described in the OP.
