Well, I figured out what the problem is. After 8-10 days of aggrivation, I finally figured out what is causing this problem.
It used to take 1 hour and 19 minutes to transfer a 19.4MB file
between my host machine (Windows Vista x64 Ultimate SP1) and my guest
machine (Windows Server 2008 x64).
I tried hundreds of hacks, but nothing worked. I've read thousands of posts from hundreds of
websites, but nothing worked. After doing much research, and testing
everything I could, I believe I have found a solution.
My host computer is a 2008/2009 Apple Mac Pro with dual Gigabit ethernet
adapters. In my particular case, I have a Gigabit ethernet adapter in
my host machine. This is the ethernet adapter in my host (2008/2009
Apple Mac Pro) machine:
Intel(R) PRO/1000 EB Network Connection with I/O Acceleration
I was experiencing the same exact slow network performance problem
between the Vista x64 Ultimate host and guest OS machines that everyone
else was experiencing.
I solved the problem by doing the following:
I disabled "Checksum Offload" and/or "Large Segment
Offload" settings on the Properties -> Advanced Settings of your
physical Ethernet adapter. That seems to have fixed the problem for me.
The problem seems to be that VMWare Workstation 6.5
doesn't like the default settings on some Windows Vista x64 ethernet
adapters (Intel Pro/1000 EB Gigabit Ethernet adapter). I wasn't having
any problems until a Windows Update (December 2008?) and suddenly
something changed, and the network folder transfer speeds were
extremely slow. So Microsoft must have done something when they pushed
out their Windows Updates for Windows Vista x64 Ultimate machines.
This is how I fixed the problem with VMWare Workstation 6.5:
First, I went into the network properties on my HOST Windows
Vista Ultimate x64 machine. I right clicked on the Local Area
Connection Adapter and went into the Properties then I clicked the
"Configure" button then clicked on the "Advanced" tab settings of the
PHYSICAL Ethernet adapter on my host machine. After click on the
"Advanced Tab" I looked under the "Property" window and I had to
DISABLE the "Large Send Offload v2 (IPv4)" and DISABLE the "Large Send
Offload v2 (IPv6)" on my host machine's network adapter.
By doing this, and after disabling the "Large Send Offload" for my host
machine's network adapter it seems to have fixed the problem, and now I
can transfer files back and forth normally, and the speed is native and
extremely fast. So the problem seems to be with "Large Send Offload"
on the Windows Vista x64 host adapter.
That is what solved my problem and worked for me, I hope this helps!
I just moved 18.5 MB of data between my host machine, and guest machine
and it now takes 1 minute and 20 seconds (instead of 1-4+ hours!

Hi,
First post in the VMWare community...apologies for bumping an oldish thread.
I'm still having issues with transfering files between Guest and Host.
It seems it is to du with my physical gigabit adapter.
A little about my setup...
I'm running VMWare workstation 6.5.2 on Win2k3 Enterprise Server R2, 32bit.
My on board physical NIC is a Marvell Yukon 88E8001/8003/8010 PCI Gigabit Ethernet Controller.
Up untill this morning I was having HUGE headaches with this problem.
I had read hundreds of links and threads to do with this issue.
I had made various changes as suggested by many people.
You know what fixed it?
I disabled the NIC completely, put in an old Intel PRO/100 Ethernet Adapter.
Problem solved.
Thing is I'm soon to be upgrading my swicth to a gigabit switch...so I guess I'll not be able to get full speed out of it to my host server.
But for the time being, I can now transfer files between gues and host.
To add to this post further - doesn't look like anyone cares anyway - I ditched VMW Workstation and installed VMWare server.
And I can use my Gigabit NIC with no issues.
So you pay for a full blown product in the form of Workstation, yet the free version in the form of Server works flawlessly.
Go figure
