mac folders mapped to windows drive are REAL slow

One of the nice features of the vm is being able to keep my data on my mac side and then access the files from windows. That way i can keep the vm small and easily backup the data with rsync on the mac....

However, I have a windows app that opens an xml project, scans through 50 or so files in the project, evaluates whether or not there are xml errors and then builds the project into an indexed book.

if the data is kept inside the virtual machine - the build time is 20 seconds or so...about as fast as doing it on a native windows dell laptop.
if the data is on the mac hard drive and mapped to z:/data/project/.... the build time is 6 or 7 minutes.
That's not just a little slower. That's unusable.
And it's not just this one windows app. It happens in any app that has to access multiple files.

Incidently, this is true in vmware fusion as well.

Any ideas why this is so?
 
What Parallels Desktop version are you using? In Parallels Desktop 5 we have made several changes to improve Shared Folders performance.
However, Shared Folders is very complex feature, and that is not that easy "just to make it fast". We are working hard on Shared Folders performance.
To help us you can provide more information about your case, so we can reproduce it in our labs and to see what improvements are required.
 
Ran across this when looking up the same issue... and have found resolution to problem. This is the exact problem I was having when mapping to a network drive (via VPN) under Windows 7 Pro running Paralles 7. It was so slow it times out most of the time.... same function on a Windows machine took only about 60 seconds for an 11 meg file.
How to solve issue - DON'T MAP FROM WINDOWS - MAP TO THE DRIVE FROM THE MAC SIDE - this way you are not using the Paralles network driver which has to act as a go in-between and interpret everything - thus the slow response.
From the Mac side - map to the network drive by:
1.- click on Finder
2.- click on "Go" on the top bar
3.- click on "Connect to Server" at the bottom of the drop down
4.- enter Server address: smb://IP Address/folder if subfolder NOTE - slashes are forward and not backward as in Windows
5.- now you will see the mapped drive in finder - and it work a heck of a lot faster.
6.- FOOTNOTE - if using this mapped drive from the Mac side rather than Windows, it is still even faster - normal speed.

Hope this helps.... caused me a lot of grief till I found the solution.
