True and if some one need more explainations, i can explain how to run MC/Rev backgrounder (console or X11 modes under Linux, graphical mode under Panther) applications servers binded, one side, to Apache trough a PHP-based sockets listener and, second side, to PostgreSQL trough shell calls to psql. I'm running such apps since years (08/2000) with great benefits in both terms of processor's idle rate (mostly over 90%) and concurrent accesses requests serving (one of those servers handle an average of 40/60 connections/second 12/24 hours).
It is just the nature of CGI programming in general. AFAIK Rev is no different than other languages like Perl, Python, TCL, etc. in this respect.
Solution 1- Switch to an ISP than has more leniency for heavily used CGI apps.
Solution 2- Stop using the CGI interface and switch to an application server environment, which generally run in persistently in memory. This would mean throwing out Rev and rewriting in another language.
Sorry Alex, you are mistaking in about solution 2 : the MC/Rev engine is able to do lots more than the documentation describe, in about TCP/IP n-tier apps. I did never use it in cgi-mode (because there are some fine Apache modules availables for that - perl, php, python,.. - and because i needed, at the begining, a solution to serve flat-files databases over the web without having to reload the files at each cgi call) but as i'm, on the other hand, handling JBoss+Tomcat+EJB2+PostgreSQL solutions (Ecole pratique des Hautes Etudes - Sorbonne, cases studies only) i can assure that the best of the java world is not in the java's engines, but in the multilayers design and dev tools (Eclipe and its great debugger, the EJB's paradigm, UML,XML, object-relational databases mapping,...).
A modified CGI environment might be able to run Rev scripts, but most ISPs don't offer such services as FastCGI or PCGI.
modified CGI environment: FastCGI, PCGI apache DSOs: PHP, Perl, Python, Ruby, etc. application servers: ASP (.NET?), Java Servlets, Coldfusion, ZOPE.
As Apache on the webservers market or PostgreSQL on the ACID compliant ORDBMS one, JBoss seems to be on the right way to eat WebLogic and Websphere...
Hope this helps,
