I strongly disagree with this. A minimal Python script using the cgi
package takes between 50 and 80 milliseconds on my (not very fast)
private server. Assuming a script which does anything useful takes about
100 milliseconds, that's still
a) a shorter response time than a lot of websites with persistent
servers have
b) fast enough not be a bottleneck on the vast majority of web sites.
Yes, you cannot run Facebook on CGI, but most websites aren't
Facebook. I doubt we have even one website which gets close to 10
requests to dynamic content per second. Much less 10 requests per
second per core.
I don't use CGI very much these days (and when I do, I use Perl - old
habits die hard), but performance isn't the reason.
