Description
The moment I turn on bridging for a guest installed on an Opensolaris host, the physical interface of the Opensolaris host the guest is bridged to, becomes sluggish to the outside world.
192.168.1.5 is my host, which I ping from another box on the same physical LAN (192.168.1.2). You can see clearly that the ping response time jumps when bridging is active (sometimes even to almost half a second).

I attached a libpcap dump from another ping session. Reinstalled from 3.1.4 to 3.1.6 to see if this problem persists (yes it does). So I'm confident that you should see this problem even with fresh installations.
One side note: my opensolaris host is serving a lot of data as NFS server, so that might play into this.
OpenSolaris Version is 2009.06.
The guest doesn't play a role here. The problem becomes apparent right at the boot loader.
