<p>Hi Klaus,<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>Thanks. It's great that you will put out the windows Shared Folders src
code.<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>As for the performance, I didn't do thorough testing, but you can get an
idea by doing this simple test:<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>share the whole host system drive, usually C:, then run notepad.exe<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>then launch map the shared drive in windows XP guest inside virtualbox,
say, you map Z: to be pointing to the host c: drive. then launch notepad.exe
by typing z:\windows\system32\notepad.exe<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>You will note that it's much slower compared to local notepad.<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>Thanks,<o:p></o:p></p>
<p> <o:p></o:p></p>
