After all this debug info is displayed i need to wait 5 min and tinycore boot .

I would have expected you to see a FTP close as well before seeing the boot.
Could you try the same thing with HTTP?

Looking on those FTP commands you have SIZE with a 550 response, no size means that ipxe can't pre-allocate a buffer to fit the file so it will need to remap the local memory for each packet received, this might very well be the issue causing the delay.

I would have tried with http or a different FTP server implementation that supports the size command to compare the speed.

I did try boot with another router that have OpenWRT installed and I noticed that instead of """status 550"" the openwrt ftp replyed with ""status 213 "" and the file size . Maybe something is wrong in the vsftpd.conf file .
Here is the content of vsftpd.conf :

anonymous_enable=NO
nopriv_user=root
write_enable=YES
local_enable=YES
chroot_local_user=YES
local_umask=000
