I've filed a bug about the performance of fuser(1M) (6878048: fuser
performance is suboptimal, which hasn't shown up on
bugs.opensolaris.org as I write this.) I've also coded up a fix that
makes the performance more reasonable. (I've requested a sponsor on
request-sponsor, but I figured I'd add m

The ithr column shows the number of interrupts that are converted to

No, this is normal behavior. The buffer cache will grow to use all of
free memory. It won't steal

Thanks for the comments.

I've submitted a bug related to this problem:
http://bugs.opensolaris.org/view_bug.do?bug_id=6801244. The gist of
this problem is that Solaris calculates the VM size of a process when
asked, i.e., when some utility like ps(1) or prstat(1M) reads
/proc//psinfo. This can be a problem on servers wit
I don't know if I need to explicitly state my acceptance, but if so, I accept.

If anyone's interested, a few improvements to ptime(1) went back into build 104.
The default resolution for ptime(1) is now nanoseconds, not milliseconds.
ptime(1) now gives you microstate accounting with the -m flag.
ptime(1) can give you a snapshot of stats for a running process with
the -p fl

around 200MB/s rather than the 256MB/s that you'd expect. Fibre
channel uses an 8-bit/10-bit encoding, so it transmits 8-bits of data
in 10 bits on the wire. So while 256MB/s is being transmitted on the
connection itself, only 200MB/s of that is the data that you
