Applies to:Oracle VM VirtualBox - Version 4.3 to 4.3 [Release 4.0]
Information in this document applies to any platform.
The environment consists of VirtualBox 4.3 (installed on supported Windows host) and a supported guest Windows Virtual Machine (VM). When attempting to transfer mass data from the host to the VM using for example FTP, it is found that with the VM's network card is configured for NAT, the time to transfer the data is much longer than when configured for bridged mode. In some cases, with the NAT mode, an FTP connection cannot even be established.
NOTE: Large File represents any large file (binary or text) but does not denote an exact minimum file size
FTP file transfer is done in Passive mode
The MTU size configured for the VM makes no difference in the performance
