[ Abstract ] Virtualization software, like WMware Player or Oracle VM Virtual Box, improves productivity and capabilities of software engineers by virtualizing some Operating System ( Guest OS ) inside another Operating System ( Host OS ). Virtualization software allows to reuse hardware to run several OSs at the same time. However, performance of processing is affected and results of testing clearly demonstrate it.

[ Summary ] Performance is affected when some processing is done in a virtualized environment: Test 1 is ~1.26x slower ( 7.918 / 6.338 ) Test 2 is ~1.37x slower ( 10.600 / 7.727 ) Test 3 is ~1.16x slower ( 16.087 / 13.821 )

Sergey,

Thanks for sharing this information. Can you share the test you are running? I mean, is it open source code?

Sergey,

Thanks for the article recommendation. I had missed this one on IDZ, and therefore, your linked allow me to know about it and read it. :)
