George, I'm just going by experience here: I've written various web stuff at various times, and found CGI versions to be slow on turnaround time - individual requests complete quickly but the overheads mount up quickly as the number of requests grow until it becomes noticeable.
Of course, I'm quite open to accept that this was down to the way I did it, and that others may have come up with better CGI based solutions. At the time I was using Apache under Linux to run shell scripts (for want of a better option) to write requests; these being picked up and processed by one or more waiting phantoms. Cheap, cheerful, reliable but slow. Whether it is down to the web server creating a process for each CGI call, overhead in the scripts writing the request, overheads on the phantom selecting for, reading and then processing the request, or time to return the data I didn't get down to investigating. I suspect it is more likely the accumulated effect of small delays at each stage. By that time I had moved on to faster solutions: generally anything running in-process of the web server and making a more direct (if pooled) connection to the database. In practice that has meant either using RedBack, small scale UniObjects pooling through ActiveX DLLs or creating ISAPI DLLs.
