Benchmarking
------------
* test/httpd-test
  - see tools/dj* for automated bootstrapping and benching of DStar 
    systems.
  - basic, min latency:
    time obj/test/httpd-test doe.scs.stanford.edu 4443 -r 100 -p /test.1?cat
  - basic, throughput:
    time obj/test/httpd-test doe.scs.stanford.edu 4443 -c X -l 30 -p /test.1?cat
  - djd requires -a for auth
  - when measuring w/o auth don't use -a, otherwise httpd2 authenticates
  - djd requires prefixing paths with www/
  - can pass in a list of front-ends:
    time obj/test/httpd-test x -c X -l 30 -p -h path-to/list /test.1?cat

* Linux
  - install apache2:
    $ apt-get install apache2 libapache2-mod-perl2 ssl-cert
  - setup ssl:
    $ mkdir /etc/apache2/ssl
    $ make-ssl-cert /usr/share/ssl-cert/ssleay.cnf /etc/apache2/ssl/apache2.pem
    $ a2enmod ssl
    $ echo "Listen 443" | sudo tee -a /etc/apache2/ports.conf
    $ cp /etc/apache2/sites-available/default /etc/apache2/sites-available/ssl
    modify /etc/apache2/sites-available/ssl
     
     NameVirtualHost *:443
     <VirtualHost *:443>
         ServerAdmin webmaster@localhost
         SSLEngine on
         SSLCertificateFile /etc/apache2/ssl/apache2.pem

    modify /etc/apache2/sites-available/default
     
     NameVirtualHost *:80
     <VirtualHost *:80>

    $ /etc/init.d/apache2 reload
    $ /etc/init.d/apache2 reload 
    (run it twice)
  - cgi:
    - just mkdir /usr/lib/cgi-bin or edit apache2 config file

  - if running a2pdf benchs:
    $ apt-get install a2ps gs

* xen
  - cut-and-paste readme:
    http://www.howtoforge.com/ubuntu_7.04_xen_from_repositories
  - front-end: stunnel+httpd+nc
    - httpd.stunnel:
    
    foreground = no
    key = /root/servkey.pem
    cert = /root/server.pem

    [pseudo-https]
    accept = 443
    connect = 127.0.0.1:80

    - some cgi script contacts app server
  - app server: inetd+nc+a2pdf
    - a2pdf:

    nc some-ip some-port | a2ps --quiet --output=- --pretty-print=plain | \
     gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=- \
     -c .setpdfwrite -f -

    - make sure inetd is started with -R some-big-num
  - data server: inetd+cat
    - make sure inetd is started with -R some-big-num
