I can't see how there would be a difference between serving 190 domains as primary vs 190 domains as secondary (or a mixture of the two). Serving 190 domains vs 140 domains may well cause a performance diff, though. This is more likely if the extra domains are popular. So, my call is "it depends", but on the popularity and total number of domains, and not on whether they're primary or secondary. :-) Richard
