Forum OpenACS Q&A: Response to Open ACS handling heavy traffic

Posted by Patrick Giagnocavo on
David asks about Slashdotting... one of the sites on my servers got Slashdotted, and did not break a sweat in terms of CPU usage; however, this was a static HTML site, with a few large files to download, which is not really typical of what an OpenACS site that got /.'ed would see.

My only mistake was that the parameter that covered the number of pages served before one httpd would exit and another start (in case of memory leakage) was too low.  It had been set for 30, but with hits coming in at 30 hits/second a new httpd child process was started every second.

I saw very high traffic, 2 GB of data go out in just a few hours.
