It seems to depend on the type of nvidia card you have. I had a T61 with nvidia card NVS140m with 128M video ram. Composite would be decently fast for a while, but gradually get very slow after a couple of hours. The slow-down could be hastened if I dared to run any video via vdpau, or restart e. ecomorph used to run fine for a while, but eventually get slow too (in about a day).
I now have a different laptop with nvidia 310M with 1G video ram. composite is really fast in this. The card seems able to run without any slowness, tested for over a week. Restarts of e or playing videos via vdpau has no slow-down effect. The difference between the above two systems was so stark that I believe my earlier graphics card (or the driver) was just not up to the mark. Also, probably composite is more taxing and unforgiving on your gpu than ecomorph/compiz (raster can confirm perhaps?). Eventually, the nvs140m graphics card died suddenly in the middle of playing a video (the infamous nvidia hardware problem). This also leads me to believe that the hardware was not up to the mark. raster has always claimed that composite was smooth on his system (that too with a dual screen setup at high resolution). I presume he has a powerful enough and recent graphics card.
