I was a mostly satisfied user of Parallels (version 2.5) but I bought the early bird special license for Fusion and have been trying it out the past few days.
One thing I was disappointed with in Parallels was the speed at which file reads and writes from a shared folder happened. I keep my subversion check-out for a company project on my Mac file system and some of the files are Windows-only binaries -- discrete event simulation files for the product Extend.
With Parallels, it was slow but usable to double click a file in a shared folder and have the Windows app open it. With Fusion I seem to have to wait 3 or 4 times as long for a double click to have the app open the file. The file is a 15 meg file so that is a factor. But Parallels could handle files of this size.
If I copy the file to my virtual disk, and double click the copy, things are very speedy but I want to keep my files where my Mac subversion client can access them.
Is this common experience -- really slow shared folders?
Any advice to speed things up? I tried to use Windows file sharing from my Mac rather than Fusion shared folders and it was no better -- might have even been worse. Mapping the share to a drive doesn't help.
Maybe this can be improved in the next Fusion release.
