[ka-Map-users] ka-map with PHP as a CGI vs. DSO?

[Stephen Woodbridge]

It would need to be set up and tested, but if you have a good size cache 
and are getting a 70% hit rate then you are generating 70% less CGI 
processes that do nothing but spool a file back to the client which 
apache does very well.

Is this "substantially better"? Don't know.
