Loadtesting on the Cheap


Firepower at your fingertips!


Why this Techtalk?

A simple excercise

Problem fixed : VARNISH!


Hey Bastian a simple riddle...
...you've got an untested Server environment with 2 Frontend-Servers and 7 up to 40 on it they get aprox. 90k - 220k Hits/Site each month.
Will this work?

Let me calculate that...

(23 Sites*155*10^3 hits/months) / (30days*24hours*60minutes) = ~82 Hits / Min...

in plain english... pretty much traffic!


Kyte from Keynote

Costs : 20k - 40k $ if a consultant plans the tests (Load Pro Plan)

An IT Company from Berne

Costs : 60k - 80k SFR

Selfmade Solution

Costs : 120 SFR

The Tools

many more like Apache Bench, Siege, curl-loader

Roll your own Loadtest

Roll your own Loadtest

Run the real deal Loadtest

Grinder in the Cloud

Loadgenerators : 10 Hosts with 3 Workers on 5 Threads = 150 parallel users at the same time

Go Advanced!

And then... ANALYZE the DATA!

The Start situation aka "Baseline"

You define the Load, The Hits, and the Paralel Threads

The end situation (after your optimisations)
