Let's not argue, because you are shooting from the hip and will just keep shooting yourself in the foot my friend :-) I posted here, not do debate performance, but to look for configuration issues related to vBulletin, but I was able to work with the folks on the vBSEO board to fine tune all those issues.
Here are some published data related to CF/S3 performance, you can review yourself.
Amazon CloudFront / S3 Small Object Test Result
Huge client side gains for using CloudFront (across the board), some as high as 95% improvement.
On a different note, related to server side apache GETs (which effects apache workers, load, etc.)
As I posted earlier in this ill-fated thread, our /clientscript traffic accounted for 30% of all our GET requests (before I moved them to S3/CF yesterday). (The static gifs are mostly gone off the server and were already served from CF globally).
Regarding the reason I posted here, I was not looking for a performance discussion, as I know the performance intimately, serving millions of PVs per month.
We are all set now..... We had a very useful discussion over at vBSEO on this.
Cheers.
