Turnaround

• The biggest improvement:

  • The client converted the CGI script into an Apache plugin module

  • No more 3000 processes

• However, I had some recommendations also

• The major one:

  • Commit the XML to a file, check it, return the status code, and exit

• A separate background process can take care of parsing it and updating the database

• The separate process handles one file at a time

• This makes it possible to control the load

  • Only one background process is running at a time

  • It can go to sleep when system load is high, continue when things cool off
