matching performance

[Adam Moffett]

I want to match several clients and give them a different option.

Is it better to do it this way:

if option agent.remote-id=0A:00:3E:F0:5C:84 {
   option domain-name-servers 127.0.0.1;
}
if option agent.remote-id=0A:00:3E:F0:7C:7C {
   option domain-name-servers 127.0.0.1;
}
if option agent.remote-id=0A:00:3E:F0:6D:3E {
   option domain-name-servers 127.0.0.1;
}

Or this way:

if (option agent.remote-id = 0A:00:3E:F0:5C:84) or
     (option agent.remote-id=0A:00:3E:F0:7C:7C) or
     (option agent.remote-id=0A:00:3E:F0:6D:3E)
   { option domain-name-servers 127.0.0.1; }

I only ask because there could be a scenario where my "several" clients 
becomes "several hundred".
