The DHCP server is single threaded so it can only deal with a single
request at a time.
Normally the bottleneck is the time it takes to ping an address to
ensure it is not already in use. I think the timeout is one second so
the server can handle an average of one request per second.
Without ping the limit is disk I/O. All leases must be recorded to
permanent storage before it is acknowledged.
With reasonable lease times, I have never seen the performance of
the DHCP server be an issue. If it is, you should probably rethink what
you are doing.
