With continual streaming of data to disks (similar to unpacking a big
archive, but worse), I found that I needed to run the following in a
system init script.
# This clears cache related to the disk. Without this
the cache grows and, it seems, bad
# things happen... Don't know if 60 seconds between
calls is best...
while [ 1 ]; do echo 1 > /proc/sys/vm/drop_caches;
sleep 60; done &
Then things stay even. Even though the targets were XFS, IIRC the
behavior was for all file systems. It is a kernel memory management
thing. Seems continual data streaming to disk is not the typical usage
scenario so things are not tuned that way.

And XFS was a complete disaster. I believe they have some kind of delayed flush, or something like that. Unpacking of 500 MB tar.xz tarball with the sources and git repository inside finished suspiciously fast, but in couple of seconds the system freezes and is absolutely not responsible for next 3-4 minutes, even mouse does not move. Yes, btrfs maybe not so fast, but at least the system remains usable the whole time.
That is the one thing I miss from good old SUSE 8-10 days, when the choice of the file system was not a question at all, ReiserFS ruled them all.
No need to cc me, I subscribe to the list ;-)
I'm glad I'm not alone in my preference for ReiserFS :-)
Is there any way we can pressure the SUSE Powers-That-Be to be more aggressive about ReiserFS maintenance and its future or is everyone climbing about the Down Train to Hell that is BtrFS?
I've joined the BtrFS list and what I'm seeing bothers me a bit and makes me think, once again, what a wonderful work ReiserFS is.
