Very long file load/save times in Windows 7 guest through vboxsvr

Reported by: Eric Carroll Owned by:
Component: guest additions Version: VirtualBox 3.0.10
Keywords: Windows 7 performance Cc:
Guest type: Windows Host type: Linux

Description

A save of a powerpoint 1.5MB file using smb takes under 3 sec. Saving the same file through vboxsvr takes up to 3 minutes.

Similarly load times are very long. Loading the same 1.5 MB ppt through vboxsvr takes over 30s, while smb is less than 4 sec.

tcpdump of wire during the load and save shows significant netbios traffic attempting to resolve vboxsvr. It also shows DNS lookups of vboxsvr. I have added vboxsvr to the hosts file without success so far.

Provider Order shows Virtualbox Shared Folders first in the list.

Disabling "Client for Microsoft Networks" and "File & Printer Sharing" did not cause the netbios lookups to go away.

Significant repeats in the vb log file of the following were found:

00:20:33.024 SharedFolders host service: request to unmap folder handle 0
00:20:33.024 SharedFolders host service: unmap operation result VINF_SUCCESS.
00:20:37.990 SharedFolders host service: request to map folder Home
00:20:37.990 SharedFolders host service: map operation result VINF_SUCCESS.
00:20:37.990     Mapped to handle 0.

Upgrading to 3.0.10 resolved the "no more files" problem but did not resolve the performance issue.

For calibration, WinXP SP3 VM with 3.0.10 guest additions: load time of 1.5 MB ppt is 16 sec, and does show netbios lookups (attached).
