Re: Re : Layer4 and Layer7 TPS

While I might not be quite so exuberant in my response, I will suggest the
Surya has a couple valid points.

 

First, however, let me say that, to the best of my knowledge, that post was
NOT made by an F5 employee.  If it is discovered that it was, it was
inappropriate and it will be rectified.  IF, however, it truly is simply one
of our customers who found some value in our testing, I’m happy to see their
excitement and enthusiasm.  I, personally, believe we do a pretty fair job
of presenting the facts; we publish the results regardless of whether we
come out on top or not and we provide complete transparency as to the
configurations of all devices, testing equipment and methodology.  Given the
report, the time and the equipment, anyone should be able to produce the
same results.  I truly believe it is as unbiased as it can be.

 

That being said, I agree with Surya the no matter how unbiased a performance
report may or may not be, the true test is how the device performs in YOUR
environment with YOUR applications and YOUR business processes.  As they
say, the proof of the pudding is in the tasting; make sure you get a true
taste.  If possible, a PoC is something we suggest all our prospective
customers do.  Anyone who has been a part of this list for any time knows
that I am a strong proponent of that philosophy.  In the end, that’s all
that matters.

 

I wish the ADC Expert good luck (Bon Chance, I believe?) in their search for
the best product for their needs.  If you have any specific questions, I’m
sure everyone in the list will be happy to give their perspective and input.

Hello.

To me this kind of "performance reports" or "competitive analysis" are just
a bunch of bullshit.

You'll find a lot of other papers on Citrix / Cisco / any vendor web site
with a lot of case studies stating they are the best vendor with the best
appliance and that the end customer is the happiest customer in the world
with his solution :)

Make a POC and setup your own load testing :)

The real L4/L7 performance in a specific configuration varies according to
the internal architecture of the product you test. Cisco ACE module
distributes the load between two NPs according to the result of a hash
function to process load balanced flows, Ace appliance relies on a single
Cavium Octeon chipset for the data plane, Citrix uses a purely software
based appliance, F5 and Foundry use another architectures (barrel processors
in foundry boxes are distributed like NPs in cisco ace module)...

When you perform load testing it's very important to understand how the box
you test really works internally, because results (and comparison) will
change with the choosen scenario that's why the "performance report" you
mention is necessarily biaised :)

regards,

Surya

Hi Experts,
   I was looking for a  ADC device that can give best L4 and L7 TPS. After
considerable search, I got few things to get clarified before selecting the
best.
   F5 has extensive performance report in its website.
   http://www.f5.com/pdf/reports/f5-performance-report.pdf
   I wonder why other vendors did not report in such detail. Even if, there
is  no free access.
   I appreciate if some one sends me across cisco, citrix and other vendors
performance details.

  -Thanks.
