I happened to format a rootfs partition and another one for /home with
Reiser4. It proved to be a disaster. Apart from the slow boot times
(expected from this drive) even after reaching a functional GUI the
disk kept doing I/O like crazy. When /home became Btrfs the issue
ceased. My other computer that uses an entire drive formatted with
Reiser4 is nice and silent as well.

Hello,
As far as I know you have to boot with a Reiser4 enabled kernel to read
reiser4 filesystem.

# lsmod |grep -i reiser4

reiser4 442368 0
# cat /proc/filesystems |grep -i reiser4 |sort

It is implied that my kernel is patched and both / and /home were
mounted as Reiser4

How large are the disks? The long boot time may be (at least partially)
caused by bitmap loading – try mount option “dont_load_bitmap”.
This won't help you with seeking *after* boot, though. It will actually
make it worse.
Do you have a proper IO scheduler set? What does
“cat /sys/block/sdX/queue/scheduler” say? (Replace sdX with the correct
identifier.)
Is there anything interesting in the system logs? I'm assuming there isn't.
