I've used SA for a year or more, but always have the network type tests turned off. My setup is at the scale of single user home lan with maybe 2-3000 messages incoming weekly.
I wondered if someone in a similar status could report what they see with the networked tests turned on. I'm not sure what all falls under that category but maybe someone could elaborate a little about which are more costly etc. I'm thinking with my light usage it may be smarter to be using them, also wondered how much more effective that makes SA.
