[ale] Issue with Virtual Box 4.2.4 on Lubuntu 12.04 encrypted hard drive

[Erik Mathis]

I run 12.04+vbox with encrypted homes on my laptop. I did move the vbox 
disks outside of my home dir because I assumed there is a performance 
hit. All night to make a small 100G file should not be. There is 
something else wrong here (assuming sata2) or something else is sucking 
up all the IO. My first guess for the missing image might be because of 
rsync's with the --delete flag (backups)? You may want to run bonnie++ 
on the disk and see if something looks wrong. btw,

emathis at emathis-lappy:~$ time dd if=/dev/zero of=123 bs=10240 count=102400
102400+0 records in
102400+0 records out
1048576000 bytes (1.0 GB) copied, 8.84721 s, 119 MB/s
real    0m9.103s
user    0m0.044s sys
0m8.397s
you should be close to that. 100G should take about 15 min to create 
according to the real time above.

anyway just my 2 cents!
