Shared Folder speed with DC++ on Virtual box is 2 to 3 times slower than DC++ on Parallels

Since trying to move from Parallels to Virtualbox, I thought I was experiencing slower io performance with Virtualbox. I couldn't find a generic free io test, so I setup a small test using bcdc++. My test uses about 200 files at between 200 and 350MB, plus a similar amount of of small files at 200-600kb, all located in a single directory.
I have timed indexing this directory of random binary files using DC++ on XP with Virtualbox and Parallels. Parallels is always 2 to 3 times faster than Virtualbox. The files that are being indexed, are on a ZFS volume. The files are accessed by a single mount of root file system exposed to Parallels and Virtualbox. "/" is mounted as drive Z. So bcdc++ accesses the directory as such, Z:\Volumes\<zfs volume name>\<zfs directory>
bcdc++ can be found here(I use 0.699d binaries): http://utrum.dyndns.org:8000/index.html zfs is here(I use 119 binaries): http://zfs.macosforge.org/trac/wiki/downloads both of these apps have source available. It would be nice if Virtualbox could be at least as speedy as Parallels.
- Summary changed from IO Speed with DC++ on Virtual box is 2 to 3 times slower than DC++ on Parallels to Shared Folder speed with DC++ on Virtual box is 2 to 3 times slower than DC++ on Parallels
