Details:

The HTTP module declares support for HTTP/1.0, which defaults to
Connection:keepalive. However, Grub's HTTP client doesn't seem to properly
support pipelining, and waits for 300ms at the end of a request before closing
the connection and opening a new connection for the next request.
The proper fix would be to notice when the Content-Length number of bytes have
arrived and then keep the connection around for the next request.
An easier solution is to have the client declare Connection:close, which will
make the server close the connection at the end of the file and allows Grub to
fetch the next file much faster.
