Quote from: "Lutz"I wonder if anybody here has experience with mod_perl, mod_python or mod_php and can tell what advantages it brings or not.

Even though newLisp has a very quick startup, It's expensive, from an operating system point of view,  to constantly start a new newLisp process for each request. For very low traffic applications forking a new process to run a CGI is probably not a big deal but once you start talking real world scenarios the expense of starting a new process for every request becomes a real problem. This is an old problem and that is why things like FastCGI, mod_{perl|python|lisp} exist.  <a href="http://www.fastcgi.com/devkit/doc/fastcgi-whitepaper/fastcgi.htm%22%3EHere%3C/a">http://www.fastcgi.com/devkit/doc/fastc ... m">Here</a">http://www.fastcgi.com/devkit/doc/fastcgi-whitepaper/fastcgi.htm">Here</a> is a pointer to the old FastCGI white paper.  If it's easy to put this together I'd suggest putting it on your development roadmap.  Serious web developers will probably appreciate it. I've been hacking around with newLisp and it shows a lot of promise, if not down right power. However you couldn't use newLisp for anything that had high volume traffic if it uses old-style CGI.  It just won't scale no matter how fast it starts up.[/url]

Sorry, should have searched the forums.  I'll check thread out. Thanks.

Quote from: "Lutz"It may not bring much speed improvement for newLISP because of its fast load time.

You have to think of it in terms of what it does to the overall system environment.  Just because you have a fast startup time doesn't mean its virtually free for each invocation.  Starting a simple C application is fast but having a CGI written in C being called hundreds of times a second on a web server starts to make the OS cranky.  That's why things like FastCGI were invented. Then when Perl showed up we got mod_perl. Sorry I'm showing my age here.

Are there any plans to create a mod_newlisp or some other mechanism for using newlisp with Apache that avoids firing a new newlisp proc on every page invocation?  I'm very intrigued by newlisp but it would be difficult to build large scale apps without some kind of support like mod_perl, mod_python, or even mod_lisp.
