Some old blog posts mentioned that Bridged is slower compare to NAT when copying a big file.
Blog Rat: Bridged vs Host-only vs NAT
Bridged - Big File Copy: Regardless of VMware Server 1 or 2, the file copying from the host inside a VM will fail when the file size is large enough. While the file is being copied from the network, the following error may occur: "Cannot copy <file_name>: The specified network name is no longer available." (Also see this)
NAT - Big File Copy: Unlike Bridged, I don't experience any file copy problem regardless of size (also see this).
