What specific techniques, such as web server configuration, vded server, back end codes, small Flash image, etc... speeds Flash load time?
having a small swf and large user bandwidth decrease the swf's load time.
What about a virtual server on quad core? Does this server configuration increase Flash download speed?
server speed is not a factor unless you have many users trying to access your files at the same time. and even then it's not a significant factor.
the server's bandwidth or, more specifically, the bandwidth alotted to your virtual server is a significant factor if many users are trying to access your files at the same time.
