EFI & PXE-booting: very slow TFTP performance on a VMWare test setup
...y the difference in time between
each DATA and ACK packet, I found another weirdness. Obviously, there is
a delay between sending an ACK after receiving a DATA packet on the
client side and between receiving an ACK and sending the next DATA
packet. To illustrate:
Client:
* receives a DATA pkt
(delay1)
* sends an ACK pkt
(wait...)
Server:
* receives an ACK pkt
(delay2)
* sends the next DATA pkt
(wait...)
Delay1 and delay2 are caused by the time it takes to evaluate the packet
and to compute what packet to send next. No fancy stuff, just some easy
calculations and memory transaction...
