Performance issue with bridged networking, Solaris host and nfs

Description (last modified by frank) (diff)
I've tested 3.0.8 for a while on my Solaris 10 U8 x86 box and it's been quite stable. I do seem to have some performance issues though. I've discovered one thing at least. When running Linux guests with bridged networking mounting a nfs share from the host, transfer speeds are really slow (4-600KB/s). This was using guest additions. Here's what I tried: Ubuntu 9.04 x86_64 guest - bridged networking
- Mounted nfs share from host (shared either using "zfs sharenfs" or using share command). File copy speed 4-600KB/s
- Mounted nfs share from a stand alone Ubuntu machine. Speed 20-30MB/s
- Mounted vbox shared folder. Speed 30-40MB/s
- PS. I often get "protocol error" messages when trying to mount shared folders using "mount -t vboxsf" but suddenly it works
Shutdown guest, changed network to NAT and booted
- NFS share from host - Speed 30-40MB/s
- vbox shared folder - Speed 30-40MB/s
- don't seem to get any errors mounting shard folders using NAT but that might be a pure coincident.
I tried with a Fedora 11 guest as well with the same results.
I've attached a VBox.log from the session using bridged networking and nfs mount from host.
