Hi,
I think the problem may be related with VirtualBox but I'm not 100%
sure.
The upshot is when I access a file on the Host O/S via a mapped
network drive, it's very slow (due to network timeouts it appears).
Please see the details below.
Comments?
Topology
--------
Network: 192.168.25.x
[bird] <---> [ zoom]
samba server + Host O/S - openSUSE 11.0
| VM - WinXP SP/2
|
+--- [ fly ]
Host O/S - openSUSE 11.0
Test Setup
----------
o Office 2007, simple PPT file with two slides, no background - file
size 37K
Test
----
o Open the file
o Change three characters and save the file
Monitoring
----------
o On the VM, running `windump'
o On the Host O/S, running `tcpdump'
Test #1
-------
Access the file via a mapped network drive to `\\VBOXSVR\my_home_dir'
Observations
~~~~~~~~~~~~
Approximately six second delay to open and save the file.
Test #2
-------
Placed the file on [bird].
Observations
~~~~~~~~~~~~
Opens under one second and saves in a little over a second.
Test #3
-------
Placed the file on [fly].
Observations
~~~~~~~~~~~~
Same as when the file is on [bird]
