It may be worth adding the noatime flag to the filesystems that hold
data and (bdb) logs. You are indexing a lot of attributes, do you
No atime? That's interesting. I've never heard of that, what does
By default, the file system is mounted with
normal access time (atime) recording. If
noatime is specified, the file system will
ignore access time updates on files, except
when they coincide with updates to the
ctime or mtime. See stat(2). This option
reduces disk activity on file systems where
access times are unimportant (for example,
a Usenet news spool).
noatime turns off access time recording
regardless of dfratime or nodfratime.
The POSIX standard requires that access
times be marked on files. -noatime ignores
them unless the file is also modified.
I think this was introduced in Sol7 or 8,
This is still not a lot files to really make a difference.
You are better off looking at forcedirectio if it is available on solaris
8. This certainly helps with sql db performance.
