My conclusion is that everything is good with VirtualBox.\r\n\r\nE.g. CentOS 7.1 x86_64 produces a box that is 343 MB and uncompresses to 358 MB with minimisation, without it would be 485 MB and 505 MB.\r\n\r\nBut comparing that with VMware where a minimised box is 444 MB, but uncompresses to **1.1 GB**! Without minimisation it is slightly worse with 606 MB and 1.5 GB. It even gets worse with Parallels where a minimised box is 407 MB and uncompressed **1.6 GB**.\r\n\r\n----\r\n\r\n_Why is VMware x3 worse and Parallels x5 worse than VirtualBox on space efficiency?_ I think we need to find out and see if there is anything we can do about it.\r\n\r\n----\r\n\r\nAll numbers I found out can be [viewed in my spread sheet](https://docs.google.com/spreadsheets/d/1jSrwB-WhxQBAjn6G6rnRl6VuPvtRsUYG-nWSB7vp2Rs/edit?usp=sharing)."}}
