file transfer speeds

Hi everyone,

I'm trying out vmware workstation 6, and have a few questions regarding expected transfer rates between guest and host os.

My setup:

host: linux mint 3.0 (which is like ubuntu 7.04)

guest: windows xp professional SP2

network: 100Mbit ethernet connection

both guest and host are on the same machine

Here are my questions:

1. First, can someone explain to me how the file transfers work? I mean, does everything go over the network, even when I'm using the vmware "shared-folders"? This seems strange to me because both operating systems (guest and host) reside on the same physical drive.

2. What's the best way to set things up so that I can seamlessly transfer files between the guest and host? Currently I have tested 3 options:

- samba

- nfs file sharing (I had to install the microsoft unix tools)

- vmware shared folders

With all three of these options, I mapped a network drive in windows explorer and then tested transfer speeds. I got speeds of 5-8 MBytes/second. Is this normal? I thought that the vmware shared folders transfer speed would be limited by the IDE hard drive speed. (but I'm probably wrong...)

3. I also tested a usb-key that should be getting 20MBytes/s write and 30MB/s read. Unfortunately, I seem to be just getting 5-8 MBytes/s...

4. Suppose that I installed a virtual machine directly on the hard drive (ie, as in setting up a special partition), instead of putting it in a .vmdk file. Would this improve data transfer rates between host and guest?

Sorry for all the questions. I've been spending lots of time trying to figure this out, but can't find anything definitive. Thanks a million for any help!

VMware Shared folder does not use networking

2. What's the best way to set things up so that I can

seamlessly transfer files between the guest and host?

Currently I have tested 3 options:

- samba

- nfs file sharing (I had to install the microsoft

unix tools)

- vmware shared folders

With all three of these options, I mapped a network

drive in windows explorer and then tested transfer

speeds. I got speeds of 5-8 MBytes/second. Is this

normal? I thought that the vmware shared folders

transfer speed would be limited by the IDE hard drive

speed. (but I'm probably wrong...)

VMware Shared folders is best when used to just move files, but the networking options you listed would be better if you need to read/write to this folder.

3. I also tested a usb-key that should be getting

20MBytes/s write and 30MB/s read. Unfortunately, I

seem to be just getting 5-8 MBytes/s...

The transfer rates are based on the CPU cycles that can be given to this task

4. Suppose that I installed a virtual machine

directly on the hard drive (ie, as in setting up a

special partition), instead of putting it in a .vmdk

file. Would this improve data transfer rates between

host and guest?

Using a physical disk to share file betwen the host and guest is unsafe and can result in data corruption

Hi KevinG, thanks for your reply! That clears a few things up. If you don't mind, could you elaborate on a few points?

-Why aren't vmware shared folders the best for read/write access to a folder? For example, would anything bad happen if I added my host's /home directory as a vmware shared folder?

\- you said "The transfer rates are based on the CPU cycles that can be given to this task". What kind of speeds should I be expecting with a dual core athlon @2.3GHz?

Thanks!

You may want to apply the AMD Dual-Core Optimizer on your host.

If you notice any timing issues

You can share your home directory, it's just better if you for example read/write to a document to use a mapped network drive and use the VMware shared folder to just move files to and from the host.
