Configuring Apache - Don't Succumb To The "Slashdot Effect"

Post date: January 31, 2006, 03:01 Category: Optimizing Views: 3920 Comments
Tutorial quote: Like many techno-geeks I host my LAMP website on a cheap ($150) computer and my broadband connection. I have also wondered what would happen if my site was linked on Slashdot or Digg. Specifically, would my setup be able to survive the "Slashdot Effect?" A Pentium 100mhz can easily saturate a T1's worth of bandwidth and my upload speed is capped (supposedly) at 384kbps, so the server should easily be able to handle that. My bandwidth will be saturated before the server is incapacitated, at least that's the idea.
