Pfilestat vs. prstat
[Just starting out with DTrace and was hoping to get some guidance.]
I have a "benchmark" program that I monitored with both prstat (prstat -mL -P <PID>) and pfilestat (from the DTrace toolkit). Prstat reports LAT values in the 0.1-0.2% range, but pfilestat reports "waitcpu" values in the 6-10%. Since those two numbers supposedly represent time waiting for the CPU,

how to debug context switching and mutex contentions?
I''m looking for a suggestion on a good way to hunt down the source of
high context switching and mutex contentions...
Is dtrace the way to go now, or should I stick with something like lockstat?

Dovecot stable slow
A few days ago I installed dovecot stable to replace uw-imap. The
install went well and all boxes were converted ok. When accessing the
new imap server though, certain operations seem much slower, in
particular, moving mail between boxes is very slow, and I have received
several complaints from users that the mail server has slowed down. I
can't figure out what the slow point is as maildir

memory allocation
hello!
First of all thank you for all your information you give us on this sites. It is a great help to learn for example dtrace.
i''ve a little script in work, which shows the cpu utilization per process in percent. this output is refreshed every 2 seconds for example.
now i want to extend this script with the output of the allocated bytes of memory per process.
how could i display this

prstat -Z and load average values in different zones give same numeric results
Folks,
Perplexing question about load average display with prstat -Z
Solaris 10 OS U4 (08/07)
We have 4 zones with very different processes and workloads..
The prstat -Z command issued within each of the zones, correctly displays
the number of processes and lwps, but the load average value looks
exactly the
same on all non-global zones..I mean all 3 values (1,5,15 load averages)
are the same

With RAID-Z2 under load, machine stops responding to local or remote login
Hi world,
I have a 10-disk RAID-Z2 system with 4 GB of DDR2 RAM and a 3 GHz Core 2 Duo.
It''s exporting ~280 filesystems over NFS to about half a dozen machines.
Under some loads (in particular, any attempts to rsync between another
machine and this one over SSH), the machine''s load average sometimes
goes insane (27+), and it appears to all be in kernel-land (as nothing

What has been swapped out?
I have a SunRay server that I am looking at to determine some sizing requirements in my department. The machine has 16G of ram and 10G of swap. Currently, I have about 4G of swap used. I am wondering if dtrace/mdb can be used to find out what lwp/processes have been swapped out?
Any hints?

Dtrace scripts for performance data gathering
I am looking for Dtrace scripts that can be used to
collect data during performance tests. I am especially
interested in IO but CPU, memory, threads, etc are needed
as well.

test67 ldap_connection
Hello,
I've been trying to figure out what's wrong with authentication
against an ldap pass/user db with test67 as test62 was working fine.
[ The problem is the same as previously described in this list :
- FreeBSD-5.3
- dovecot-1.0-test67
- openldap-2.1.27
--> "ldap(dovetest,127.0.0.1): No password in reply"

ZFS slows down over a couple of days
Hi all,
I have exchanged my Dell R610 in favor of a Sun Fire 4170 M2 which has
32 GB RAM installed. I am running Sol11Expr on this host and I use it to
primarily serve Netatalk AFP shares. From day one, I have noticed that
the amount of free RAM decereased and along with that decrease the
overall performance of ZFS decreased as well.
Now, since I am still quite a Solaris newbie, I seem to

Compressed maildir
Greetings,
I noticed a while back someone posted a patch/plugin that allowed Dovecot to
use compressed mbox files. I'm now wondering how far that would put us from
having compressed maildir? I have a server with more CPU than disk space, and
while I can buy more HDD space, my backup solution doesn't make that practical.
It seems to me that when looking for a message file, if it

attr_names in test67
Hello,
I'm wondering if the following situation is valid (though I think it
isn't since I still cannot authenticate with ldap pass/userdb on
test67 running on FreeBSD-5.3).
Is it normal that the passdb_ldap_conn->attr_names second element (for
instance) "turns to" "homeDirectory" as the following step by step gdb
run sample shows ? :

test73 not compiling with iconv?
I've recently upgraded from test53 to test73 from a source compile on
FreeBSD 5.3, and am getting some [BADCHARSET] errors in 73 that I
wasn't getting in 53 (specifically with Squirrelmail).
When I run one of Squirrelmail's built-in filters, I get the
following error:

1.0-test67
http://dovecot.org/test/
Hopefully better release than last one. Fixes several problems test66
had and also some older problems reported in this list.
It also contains a pretty large mbox code cleanup, fixing several
problems (especially related to X-IMAP/X-IMAPbase headers) and making it
a bit faster. Maybe I'll backport it to 1.0-stable too when it looks
like it's stable..

password_verify in test67 with ldap
Hello Timo,
your patch introducing pass_attr_names and user_attr_names fixed the
problem of the 'shared' attr_names member of [passdb|userdb]_ldap_conn
as I answered in the relative thread.
Now I think there is a problem while comparing user-provided and
ldap-provided passwords causing a false 'password mismatch' situation,
while using PLAIN mechanism with LDAP authentication.

1.0-test73
http://dovecot.org/test/
Two potentially dangerous changes:
- mbox parser should now be able to handle CR+LF linefeeds. Hopefully
doesn't break anything.
- Some mail header parser changes. Hopefully doesn't break anything.
And other stuff:
- COPY shouldn't crash anymore with 64bit systems
- If PAM modifies username, keep it
- When auth workers died they leaked file

Aggregation elements
Howdy,
Is there a method to get the number of elements in an aggregation? Are the
results stored in an aggregation guaranteed to be in any type of order?
Thanks for any insight,

expected system load from DTrace scripts/probes
Does anyone out there have any thoughts on the type of load common
DTrace scripts would cause on a system if run 24x7? I know "common
DTrace scripts" and their underlining probe calls a vague statement. So
for the lack of a common and establish set of scripts in the OS, I''ll
