What kind of traffic did you get?
Average load/Max load, number of requests etc?.

273M requests on 823 days gives 3.84 req/s average so it's not so much.
There are also requests for static content which are handled by apache and
not counted here.
I don't know the max load but on that old server the lisp process can serve
1440 req/s so we are very far from that.
The server load was generally around 0.2~0.5%

What web server did you use?

Apache + mod_lisp + my webapp framework.http://www.fractalconcept.com/ilc2002-marc-battyani.pdf

Now it would be called an Ajax framework but I don"t even know if the
acronym already existed in 2000/2002.

Just curious.. (I also use LispWorks and am considering it.)

This is with LW 4.4.6. When I upgrade to a new server I will switch to LW
5.x

LispWorks 5.x support pthreads on Linux, but all pthreads can only use
ONE cpu at the same time. So if you have only one Lisp process
running, it's better to use a high GHz but multi-core CPU on your
server.

What does that buy you? The OS makes each core appear to be a
separate CPU. A Lisp that's limited to one CPU will only use one
core.


May another way to pass this is let multiple Lisp Web process
listening on different TCP ports, and use Apache's Proxy and Rewrite
URL support, Squid, or even LVS to make a "Virtual" 80 port for all
these processes.

I don't know if LW on win32 can use multiple CPUs.
