Ticket #12161 (closed defect: fixed)
EFI boot very slow with Serial Port enabled => fixed in SVN/next maintenance
| Reported by: | AxelFontaine | Owned by: | |
|---|---|---|---|
| Component: | EFI | Version: | VirtualBox 4.2.18 |

Description
When booting a VM using EFI with a serial port mapped to a file, the VM spends more than 10 seconds in EFI before booting the kernel. During this time a lot of output is written to the serial port file.
With the serial port disabled, the same VM boots the kernel after less than 1 second.

More testing with 4.3.6 completed.
This problem is Windows-only. It works fine on Mac & Linux.
It also has gotten worse with recent releases. The boot now takes even longer.

Sorry for the very late response but I just stumbled over your ticket. The issue is still true with the current VirtualBox release but will be fixed in the next maintenance release. Thanks for the report!
