When scaling up to 512 Virtio-net devices SeaBIOS appears to really slow down when configuring PCI Config space - haven't manage to get this to work yet.
If there is a slowdown in SeaBIOS, it would help to produce a log with timing information - see: https://www.seabios.org/Debugging#Timing_debug_messages
It may also help to increase the debug level in SeaBIOS to get more fine grained timing reports.
