Folder redirection and network performance

I came into a new IT environment a while ago, and we have just one Windows 2003 server supporting about 60 client machines. The previous IT admin set up folder redirection for users My Documents folder. Our server is clogged up all day since it handles Exchange, file and print sharing, as well as being a regular application server.

I suspect server performance could be improved by taking out folder redirection, but I want some metrics to support it. Are there any good metrics I can use in a windows performance log to link server usage with the folder redirection?
