[TYPO3-Performance] ab failed requests

[georg kuehnberger]

Dan, Dmitry, et al,

FYI only: We recently had a requirement to load-test an application with 
something like 20.000 concurrent users doing personalized logins, some 
user-activity-within the application and logout within 5 minutes;

Having spent a day or two on developing the testcase, allocating "free 
machines" as test-slaves and running our load-tests we soon faced the 
following limitations: number of available-testboxes, effort to setup 
new testboxes, cpu, filehandles (aka network-connectsions), overall 
available bandwidth, and even more.

So we turned to on-demand cloud-computing and were able to work around 
the above limitations by simply adding (or removing) more "cloud-boxes" 
to our "bank of clouds" in a matter of minutes/hours rather than days.
This move allowed for the targeted "cloudburst" towards the AUT 
(application under test), and meaningful analysis there.

I definitely fell in love with clouds; however only in the computing-sense.

cloudless, sunny greetings
regards georg
