 | View Full Version : Hardware for 100.000 users ? Wallker 11-26-2002, 02:33 PM I have a little question about hardware. Which hardware do you recommend for 100.000 simultaneous users on a server (cluster). The webpage is only in PHP writen. Best regards from europe Wallker MarcD 11-26-2002, 02:58 PM What type are you talking about like cpu memory hd that kind of hardware ? what size are the loads ? 100 is a lot to be running all at once Wallker 11-26-2002, 05:05 PM Yes i mean CPU and memory. Harddisk is a known thing. My customer needs 100GB. But my problem is the other harddware. I think that two dual-XEONS are not enough for this. What do you think? admin0 11-26-2002, 05:18 PM maybe 2GB RAM and dual 2ghz p4's ? depends on what will the 100,000 users be doing all at once ? :homer: timelord 11-26-2002, 07:11 PM While the numbers are from older machines, they should still be helpful. In 1999, testing I saw on SINGLE processor systems were reporting 1500 static web pages/second for machines in the 733Mhz range. (PHP generated pages would of course be less [about 25-50% less].) In theory (and yes - I know that things don't scale lineraly), a dual processor system should then be about 3000 static web pages/second. If we presume that today's machines can handle twice the load - you are talking about 6000 static web pages/second/machine. So, for 100,000 web pages/second - you would need AT LEAST 17 servers (and more then likely more than that so that you could have N+1 redundency, etc.) There are some real good articles at http://activeanswers.compaq.com that describe capacity planning for web servers (look under the DISA section). And they even have a sizer available. |
