Memory usage with memdisk vs initrd a squashfs
Question,
Some Linux distributions I support show two approaches for pxe booting them. One uses memdisk to boot an ISO file. The other uses pxelinux to boot kernel and initrd a squashfs file.
I'm unfamiliar with the impact to memory either approach has. Like, does using memdisk permanently squirrel away a chunk of memory for the ISO file that the OS will be unable to use? Is using initrd to

...another file will be
more efficient (an ISO might have extra unnecessary stuff like a copy
of the kernel and initrd) and would load faster. In my experience
TFTP with PXE tops out around 1 MB/s while an HTTP load can easily see
17MB/s or more. lpxelinux.0 (the lwIP-enabled PXELINUX for BIOS) can
achieive this as can gpxelinux.0/ipxelinux.0 or PXELINUX ontop of
gPXE/iPXE. You can also see this when loading the file after the
kernel is booted which would often be a little bit faster than
HTTP-capable PXELINUX.
