Hi there, From the Nessus scanner's point of view, your concern should be what the maximum number of systems that can be scanned at one time. The settings "number of hosts in parallel" and "number of checks in parallel" should be where you make your optimizations. If you had one scan that did 30 hosts in parallel with 10 checks in parallel, this would be similar to three scans occurring at the same time which only did 10 hosts in parallel. If you look at this blog entry: http://blog.tenablesecurity.com/2007/01/optimizing_ente.html and pay close attention to the output of plugin #19506 http://www.nessus.org/plugins/index.php?view=single&id=19506 you can see which hosts are taking a long time to scan and perhaps minimize your scan time. Also, during the scan, if you watch CPU and memory usage, you might be able to figure out if your scans are being too aggressive. If you have too many scans competing for resources, you might get faster overall performance by lowering your total number of scans occurring at the same time.
