Wireshark, Statistics, IO Graph, "udp.dstport == 1719", bits/tick. Look at both 1 second per tick and 5 pixels per tick and then 0.1 seconds per tick and 1 pixel per tick. -- -Gene

Is in this thread also a newer TFTP-server being tried? Groeten Geert Stappers [1] http://www.syslinux.org/archives/2015-October/024468.html -- Leven en laten leven

I've been trying to dig into this issue and it appears it's mostly in the gnu-efi callbacks or the UEFI firmware gnu-efi calls (if I trust my tests and the custom timer I just made). -- -Gene
