this is one very weak area for *. There is NO ANSWER.
Now in fairness to *, the answer DOES depend on a # of critical variables.
How much CODEC to CODEC transcription is going on.
How many MEET Me conferences are going on.
On the other hand, DIGIUM COULD, since they have a lab take 4-5
'standard' workloads
on two of the most common hardware boxes, say Dell & HP, and run x # of
transcriptions and
show the #'s.
Then x # of meet-me conferences.
Face it the DB Industry did this 15-2- YEARS ago with TP benckmarks
Rockwell and NORTEL can tell you this for every piece of hardware they sell.
It is a an area DIGIUM need to "man-up" in.

Hi,
There have been a couple of threads on this subject this week, so I'd
remind everyone that next Friday's VoIP Users Conference is about
*large scale* asterisk:
After many requests, we finally have someone to talk on large scale
implementation of VoIP systems with asterisk. Using a farm of Asterisk
and Digium cards, tens Of Thousands of simultaneous calls can be made
and Mike Trest has offered to take it all apart for us to look inside.
More about Mike Trest: http://www.mike.trest.com/ |

I wonder if there's a proportion where somebody could take some
standard kernel output, say bogomips,
and guesstimate some proportionality from that. As in: bogomips says
this, expect ballpark 120 SIP over codec calls.
It certainly seems like there could be some kind of asterisk
benchmarking utility kindof like Sandra for Windows. I know there are
a gazillion variables in asterisk, and that's why asterisk is so
powerful. But some benchmarking utility would at least allow some
(even if phony baloney) relative comparisons between similar hardware.
Has anybody ever tried to roll their own VoIP or Zaptel load
simulator? How did they do it?

I'm not sure what your problem is with Digium. They sell several machines
for which they publish very specific numbers as to how many users those
machines will support (the Switchvox appliances). Note that these machines
are configurable only from the web interface, and they do not allow you to
install additional software. In other words, when they give you a specific
machine, with a ton of those variables controlled, they can give you a number.
Digium is under no obligation to give you numbers for your own hardware.
That's up to you (and you get to control your own set of variables).

Since one standard answer to this question is: "it depends on how
you're using it",
The ideal situation is that people could rattle off statistics of
their eventual load, and be able to size their hardware purchase
accordingly. The reality is that while that's hard, we can do the next
best thing, which is once you have the hardware running asterisk, get
historical data about your real-world asterisk load.
We're running the open SNMP daemon, and we've configured the open
software project Cacti to do SNMP polling against our cpu load. We now
have a few months of data on how two systems running Zaptel cards,
with no VoIP are holding up under load. Our business is amazingly
seasonal, not quite as bad as H & R Block, but similar scenario where
we're very busy parts of the year, and the rest of the year, not so
much.
Our results: at our US Eastern time zone business, load peaks a little
after 2pm EST/EDT, most business days, and dramatically tails off most
days. Once we have more months of data we'll also be able to more
accurately profile the seasonality of our business, as well as make
some predictions about next peaks from previous peaks, given the
growth rate of our business.
Hope this helps people! |

SIPP can help with benchmarking SIP calls and you can loop back T1
calls if you have two machines with T1 cards or even one machine with
multiple T1 ports.
Then just look at top. Make a few test calls and see if they are choppy....

SIPp looks like it's exactly the right tool for voip load generation /

Tilghman,
It seems any constructive criticism offered, you take as an attack
against Digium. That is not a good attitude.
While under no obligation, it certainly would help sales.
I take "Appliance Numbers" with a grain of salt. The sales model of
SwitchVox (and most others) is based on number of ports (SoHO, SMB,
Enterprise) not maximum number of ports that the appliance could
actually handle if not artificially constrained.
This is in the style of legacy proprietary systems and anther reason
why the sale cycle goes a little tougher than a custom job. Asterisk
with FreePBX (and maybe Druid) eliminate these artificial constraints
on usage.
I have load averages and CPU usage stats in my mind for all the
various usages and hardware through experience in my mind. Of course
they are only valuable to the exact setup I was doing.
Thanks,
Steve Totaro |

To prove that the the numbers are artificial for SwitchVox and profit driven:
Boot your SwitchVox in single user mode. Create an account with root
privileges. Login via SSH and you can install any software you want
and have access to top and whatever else you care to use. Switchvox
is running Fedora Core 6 and Asterisk 1.2 just an FYI ....

You can NOT use bogomips as any kind of measurement for system performance.
First of all, Bogomips is a linux-specific thing and not available on other OS that Asterisk runs on.
The second, and far more important point. "Bogo" is taken from the word "Bogus". Bogomips are not a measurement of system performance, it is simply a number used for calibrating parts of the kernel for your CPU.
The problem with coming up with these numbers of concurrent calls is that Asterisk is not a "complete package". Meaning, it's the software portion only, most other systems when you get them are going to be the software & the hardware in one package, the 2 go hand in hand and are specifically designed for each other.
Asterisk does not fall into that category unless you invest in one of the many asterisk appliances out there. Digium has no control over what hardware you are going to run Asterisk on, so they can't provide you with these numbers.
Heres a few questions at the top of my head that I think would influence the answer:
are you recording calls? are you transcoding calls? are you using T1s or SIP/IAX trunks? Did you buy the 7.2krpm, 10krpm, or 15krpm hard-drives? Do your harddrives have 8mb, 16mb, or 32mb cache? Did you buy the better SAS controller? Did you buy 667mhz or 800mhz ram? Are you using EXT3, ReisferFS, XFS, JFS, ZFS, UFS? Are you using AGIs? Are you using MeetMEs? How many? Whats the average length of the conferences? Are devices using re-invites to take Asterisk out of the call loop?
The list goes on and on... and every single one of those answers is going to influence that number for "How many calls can my system handle?"

Concurrent users is only valid if you can specify what all of the concurrent
users are doing.
If you have 13 users engaged in phone conversations, you have a different
load and system
dynamic versus 4 users in conversations and 9 users checking voice mail and
perhaps recording
new greetings.
The artificiality arises when you use your "concurrent user" figures to
portray your product as better
than the other guys without qualifying what the "concurrent users" are
doing.
|
I am very aware of this but do you think that the SoHo box (and it's
artificial cap) is maxing out no matter what the users are doing? If
so, then why can you just upgrade concurrent use via a CC and the
website?
I don't have a product per se. I am generally against "Appliances"
because they are moving back to the proprietary system pricing scheme
of per port and cut my bottom line. They also generally have a lot of
legalese attached.
My "product" is built to meet the current and future needs of the
customer. This is all part of the sales and quoting cycle.

Consider the maximum number of ports that Switchvox will enable on a single

comfortably without running into some hard limit. You never want to run into
a hard limit in the field anyway.

Yes, but the point of those constraints is to permit support a manageable
job. Yes, you could probably add 2 or 3 or 10 or 15 to the number of calls
that a particular machine could handle, but from a support perspective, it
doesn't matter how many the machine could theoretically handle, it matters
how many it could handle in the particular installation in a supportable
configuration (those are all those pesky variables we've been talking about).

Sales in general. You don't need to benchmark everything, just a few
basic benchmarks, maybe gear it to your hardware and SIP as a gateway,
then build from there. Most companies do this.
I have my own lab and bechmarks but they are for Sangoma hardware and
very specific servers and all geared to callcenter apps.

job. Yes, you could probably add 2 or 3 or 10 or 15 to the number of calls
that a particular machine could handle, but from a support perspective, it
doesn't matter how many the machine could theoretically handle, it matters
how many it could handle in the particular installation in a supportable
configuration (those are all those pesky variables we've been talking about).
|
Maybe that is what the official corporate answer is or, you were
brainwashed to believe, but I tend to think it is to sell SMB and
Enterprise software and support. It is all about money. I didn't
fall off the turnip truck yesterday.

Precisely.

While under no obligation, it certainly would help sales.

Whose sales? If you're talking about the appliances, then yes, I'm sure
the publication of those numbers help with sales. If you mean your own
sales, well, you're right, Digium's numbers probably don't help your
sales. You could certainly put together a lab and do your own testing.
Why don't you do that?
|
Sales in general. You don't need to benchmark everything, just a few
basic benchmarks, maybe gear it to your hardware and SIP as a gateway,
then build from there. Most companies do this.
|
Precisely. The numbers Digium gives are geared to their own machines.

Now who's on the attack here? Instead of taking issue with the logic, you're
personally attacking me, and I do take offense. The logic is sound, and it is
precisely the reason why we say "X machine supports Y users". It makes it
easier for the support department, that they don't have to deal with edge
cases of "Well, if you're doing the maximum transcoding AND recording AND
conferences AND a few other things, then maybe it won't support Y users."
No, we want the numbers solid; we never want it to be said that we sold what
we could not support.
