Hello...

My kernel asked me to increase NBUF and BUFPAGES. I thought, that
tweaking of buffer sizes was not necessary with UBC anymore? Or am I
mistaken? Where can I read about those values in more depth?
options(4) does not seem to tell that much...

Here is the request:

lfs_mountfs: please consider increasing NBUF to at least 2100
lfs_mountfs: please consider increasing BUFPAGES to at least 4311

The system data:

NetBSD-current (i386) from two days ago. The mentioned LFS:
