Slow NAT networking on opensolaris 2008.11 64bit host
Hi I use opensolaris 2008.11 64bit on my file server and was very happy to see that VirtualBox 2.1.0 fixed the NAT problems that crashed my Windows XP guests every five minutes. My problem now is that im only getting about 0.5Mbit when i upload or download files to the cifs server on the host. and when I U/D files from other cifs serves on the network.
I tried to create a Debian etch guest, but had the same problems with network speed.
I then copied the guests to my workstation (windows XP 32bit) with Virtualbox 2.1.0. there were no network speed problems when i ran my file tranfer tests from the same guests but with an XP host
Back on my opensolaris server i switched the guest from NAT to host interface and tried the same file operations over the network. no speed problems.
after these tests i can only conclude that there is a speed problem with the Virtualbox NAT engine on my opensolaris server
please let me know if you need more informasion, or if I need to clarify something in my description
