measuring iops on linux - numbers make sense?
Hello,
When approaching hosting providers for services, the first question
many of them asked us was about the amount of IOPS the disk system
should support.
While we stress-tested our service, we recorded between 4000 and 6000
"merged io operations per second" as seen in "iostat -x" and collectd
(varies between the different components of the system, we have a few

Performance of Maildir vs sdbox/mdbox
Hi Guys,
I've been desperately trying to find some comparative performance
information about the different mailbox formats supported by Dovecot in
order to make an assessment on which format is right for our environment.
This is a brand new build, with customer mailboxes to be migrated in over
the course of 3-4 months.
Some details on our new environment:
* Approximately 1.6M+

IOPS required by Asterisk for Call Recording
Hi
What are the disk IOPS required for Asterisk call recording?
I am trying to find out number of disks required in RAID array to record
500 calls.
Is there any formula to calculate IOPS required by Asterisk call
recording? This will help me to find IOPS for different scale.
If I assume that Asterisk will write data on disk every second for each
call, I will need disk array to support minimum

1 week after full migration to 1.1v
Ehlo all,
I've been working on a migration of about 240K users from one server
with qmail, courier imap, maildrop and ldap to postfix, dovecot, lda
+sieve. Before the migration the server and the storage were always on
high load.
Before migration:
Storage IOPs = 4600
Read average = ?2800
?Write average = 1800
Storage CPU (Raid5)
Crl0 = 50%
Crl1 = 50%
Server Load = 120

deliver and qmail
Hi all,
ok, after looking at all of the posts that I've found, and trying
numerous settings, I am a little stumped as to how to set up the deliver
program with qmail to get everything correct.
Ultimately, I really don't want to do a lookup of the home dir if I
don't have to. I'd rather specify the stuff in the .qmail-user file for
that particular user to avoid the extra step.

[storage-discuss] high read iops - more memory for arc?
Pre-fletching on the file and device level has been disabled yielding good results so far. We''ve lowered the number of concurrent ios from 35 to 1 causing the service times to go even lower (1 -> 8ms) but inflating actv (.4 -> 2ms).
I''ve followed your recommendation in setting primarycache to metadata. I''ll have to check with our tester in the morning if it made

Sending voicemail with qmail
you can do that. But are u installing qmail and * on
same box. i wont
recommend that. i use qmail and *. qmail is strictly
for internet email. *
is on separate server not exposed to Internet. * box
also has sendmail. i hv
configured sendmail to use smart host (qmail server).
This way its safe and
secure.

qmail-remote uses 100% CPU when delivering to certain hosts

Firstly, my environment:
