This page is to collect a list of benchmark results available and demonstrate not only the words about containers technology being more superior from performance point of view compared to hypervisors but also to provide some data proving that.
−
The aim of this benchmark is to measure how fast can application inside of virtual machine (VM) or operating system container (CT) react on external request under various conditions:
 
−
* Idle system and idle VM/CT
 
−
* Busy system and idle VM/CT
 
−
* Busy system and busy VM/CT
 
  
−
Described benchmark case is common for many latency sensitive real life workloads. For example: high performance computing, image processing and rendering, web and database servers and so on.

To measure response time we use well known netperf TCP_RR test. To emulate busy VM/CT we run CPU eater program (busyloop) inside of it. To emulate busy system we run several busy VM/CT (to eat all the host CPU time). Netperf runs in server mode inside of '''one''' VM/CT. On the separate physical host we run netperf TCP_RR test against selected VM/CT over the 1Gbit network.
