Are there any physical limitations to the number of connections
(TCP/UDP) that are determined by the physical interface itself?
Sure. Divide the interface speed by the size of the smallest packets
one can send including ethernet preamble, all headers, and the
minimal gap between frames. There's a PDF here with all of the details:
...but for 100Mbs full-duplex, you can send up to ~150 Kpps of
minimum-size packets, or ~8 Kpps for max-sized packets.
We have a PF load-balancing solution in place in front of a large
number of mail
servers and we're considering using the same boxes to front our Name
Server/Name Resolvers. I'm concerned that the single uplink port
PF box will be overloaded with the number of connections.
Any insights would be greatly appreciated.
One hopes that your "large number of mail servers" are only sending
