Radimus, Do you really think it is beneficial to copy the SP locally and then run the install?

I did some tests (nothing in great detail) with XPsp1 and 2Ksp3 and found that uncompressing the service pack to a directory on a server and then running update.exe from the client machine and letting the client pull what it needed was consistantly faster than copying the entire SP locally and then executing.

Just curious to hear your thoughts.
