starting a make world. I stopped it after I noticed that the disk was getting
an incredible pounding during C compilations that previously would be
almost totally CPU-bound. My impression from "systat -vmstat" was that
somehow the effectiveness of the namei cache had gotten drastically reduced,
and the lookups of the names of include files were causing a lot of disk
Has anyone else seen this?
Same here. Very very slow (I was compiling sendmail, guess why ? :-))
Same here. `du -a /var | wc' accesses the disk every time to stat only
I suspect revision 1.30 to vfs_bio.c (1995/02/22 09:30:13) broke
something. It was supposed to _stop_ the buffers associated with
directories and metadata being thrashed by regular i/o. My
getnewvnode() stops some of this thrashing (and thrashing of file data)
by preferring to reuse vnodes with no attached buffers. Before
1995/02/22, this increased the maximum amount of directory and metadata
info by a factor of about 10. I want it to be increased by another
factor of 10.
