Generally Cisco devices (apart from some of the very latest platforms)
have reeeeaaaaallllyyyy slow flashdrive IO. Since XR accesses the flash
drive all the time (and has a lot of data), this makes it slow as well.
I've been told the upcoming replacement RP for CRS-1 has SATA SSD and is
a magnitude (or more) faster than the old RP when it comes to
installation and booting due to more CPU and especially a more sound IO
hardware subsystem.
Even a Cisco 1841 loads IOS many times faster from a USB stick compared
to the built in CF, and a 7200 boots faster over ftp than from the built
in flash cards.
It seems Cisco has finally realised the problems with their IO subsystem
so I hope newer devices will work a lot better.
I think only explanation here is Cisco had large stock of quite old
CF-readers/hardware which is slow as hell(because of age) and thus still
installing them. Because I can't remember any recent and even 2-3 years
old CF cards or CF-ATA adapters that slow.
Or IOS implementation of IO is just plain suck, whatever this is
low-level access or VFAT implementation problems. It can be fixed via
software update.
