Ok, let's see. We've got a few what I would consider medium-weight sites. All database backed (local PostgreSQL server). They are all primarily web/information sites, although we have few "web application" type situations. In a few months we'll be finishing a very large scale web application running on Webware/Postgres, but that doesn't help you now. Most of our sites are PSP-based, but with all the logic held in Servlets that the PSPs inherit from. Some are very dynamic, some less so. Example one: a customer with a couple thousand product combinations, who gets a medium amount of traffic, although it varies heavily based on day and hour. Monthly average is about 70,000 page hits, but this is generally concentrated into afternoons with 10-15 per minute. All with several sql queries / joins per request. average 0.5 seconds per product page, from webware's Activity log. Example two: also on this server, we have about 10 other webware-driven sites that don't create as much load individually, but perhaps combined are 2-3 times that load. This is all from a single webware instance, as contexts. This server (1Ghz, 1GB mem Dell) shows no significant loading. Example three: artificial load testing of our database environment. we've got two test pages: one that makes a large join query and then uses python to cycle through the results (several logical levels, several hundred results), and another that makes several million select queries in a recursive loop. The first consistently serves in 2-8 seconds, the second in 15-40 seconds. We've run our test scripts with between 5 and 20 concurrent agents, making hundreds of requests. Not terribly scientific (I'm running ApacheBench right now against our test pages.... almost exactly the same general results), but perhaps some help. Also, we've had very enjoyable success with our combination of webware/apache/postgres, so we are currently in the middle of developing a large-scale application (10K's total users, 100K's transactions/week... haven't run more in-depth projections) using it. But this promise of large app development doesn't really help your immediate need of examples. - Luke ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/ ------------------------------------------------------- This SF.net email is sponsored by: Etnus, makers of TotalView, The debugger for complex code.
