Thats a lot of NMBCLUSTERS, but if you've got the memory you should be

Yes, netgraph. See "man ng_one2many"....

I actually had the NMBCLUSTERS set that way even with 128MB boxes without issues but 
the box in question has 2GB of ram so it's not much of a big deal.  I tried the 
ng_one2many and it did help bring things closer to 80Mbps from 60Mbps.  I guess the HD 
is the bottleneck as it's only a notebook and even with the 7200rpm 60GB 2.5" drive, 
the sustained transfer rate is limited.  Tried the HZ 1000 setting and recompiled a 
new kernel but it didn't really seem to do anything at all.  I'm wondering what's the 
highest setting it will work with.Thanks,John
