Extremely slow file transfer rate when copy files between host and guest OS (VMware Server)?

Today I managed to resolve a 2-day performance issue with copying files from the host running VMware Server to any guest OS (VM) and vice versa. Luckily I found a solution from VMware Knowledge Base:

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1006619

It is a known issue with VMware Server host running in Windows Server 2003 or 2008 environment.

Cheers~

  1. Having similar issue on Windows 7, but registry structure differs. File I/O between SMB shares on guest Linux VM are suuuuuper slow on my 7 machine at home, but fine on my 7 machine at work :/

    1. Have you tweaked the Registry setting on both 7 machines at home & work? This is an issue related to the host not the VM. Or perhaps you may try other network mode such as NAT or Host-Only if you do not require Bridge all the time.
