I have noticed the PXE Booting process seems to be getting really slow now under both LDMS 9.5 SP1, SP2 and LDMS 9.6 SP1. I remember it used to be fast back on LDMS v9.0 SP3.
Like yourself Miw, I too have been looking for some TFTP settings / registry key values to edit to increase performance but to no avail to date. So if anyone have any ideas on how to boost performance and could share, that would be great.
